Last night (Wednesday) around 11:30 at Sal's Pizza on 7th and A, Johnny Knoxville stops in for a slice with a slip of a brunette who most certainly did not order pizza. Johnny was wearing an unfortunate pair of cut-off turquoise pants with an ass so oversized it looked like he was sporting a full diaper. Aforementioned brunette just might have been the right age for a diaper.

Saw Clive Owen yesterday is Soho, walking on Houston and crossing West Broadway. Taller than I expected. Stubble and chewing gum with his mouth open. Dark sunglasses and stringy hair. He's very gangly in person, but is still super sexy and has a very strong, handsome face. The big letdown was his ass—he doesn't have one.

Saw Julia Roberts on Sunday for Spamalot matinee. She and her husband Danny Moder were sitting two rows in front of me. She wasn t wearing anymakeup, hair was in a bun, but still looked naturally beautiful. At intermission, her husband waited with her while she stood in line for the bathroom. He is a hunk in person. Not many people noticed her except for one thirteen year old girl who bumped into her on the way out of the bathroom and then proceeded to skip to her parents and yell. Two minutes before the end of the show the security guard came and whisked them away before the lights came up. Despite what one might think, she did a very good job at being discreet and non-descript. Soo not the way I d ever want to live

Brunch at Cafeteria on Sunday 5/1- J.Lo was keepin it real with the commoners. Accompanied by her sister, Lynda, (who is way taller) and another girl, maybe sister or family member. All in all she looks pretty normal, i wouldn't have noticed her if it weren't for the news of her arrival going around Cafeteria like a game of telephone. They made JLo, sporting stealth aviator sunglasses, wait about 10 minutes for a table, in the meantime she and the other two hung out by the bar.

Saw Usher monday night (May 2) leaving Trump Hotel. He was with a bodyguard and two other people..surprisingly he carried his own umbrella.

It was a good day for celeb-spotting in Central Park today despite the brisk weather. First I saw Ashley Olsen on her cellphone, walking very quickly with her head down as two teenage boys in front of her stopped and turned around every few steps. Green capri pants, tan blazer, flowered scarf-as-headband. Cute girl. And then, and then...I spied Tara Reid, coming out of the Time Warner Not-a-Mall-But-Really-a-Mall with two friends - another blonde girl and Tommy Lee. The trio debated taking a pedicab as Tara, voluptuousness on display in a tight yellow t-shirt, informed them that "I've never done that!"

Saw Diane Keaton entering the St. Regis Hotel at 55th St. on Saturday night at about 7:30 with another woman. She looked very friendly; she smiled even though my friend and I were clearly gaping at her. Looked exactly as you'd expect (very Annie Hall): wearing all black, a hat, and sunglasses even though it was a) raining and b) dark already. We overheard the doorman tell someone that she was staying there and that she was cool.

Late lunch today celebrating my ongoing unemployment- at Balthazar, 3PM. The worlds finest actor- or not....Kevin Costner, looking like a midwestern dad, with wife Christine, who was showing way-too-much cleavage for lunch- she also looks at least 6 years older than the 29, 30 she claims to be...Also, Michael Shvo, wearing a really expensive and fine looking suit, attached to blackberry, getting VIP treatment, and with girlfriend- only girlfriend was wearing a top from H&M (white linen long cami with pom poms) The Millionaire Schmo should take her shopping for some good stuff...

Saw Daniel Day-Lewis and Rebecca Miller with their welp waiting for the light at 6th Ave. and Christopher Street on Monday afternoon. Still kicking myself because I didn't think to check out their shoes until I was too far away to get a good look.

You probably are getting a bunch of emails about this .. BUT, last night at Irving Plaza I saw Beyonce and Jigga checking out Island/Def Jam emo flyboys Fall Out Boy. The couple (with 7-foot bodyguard) were perched above the sweaty pit of Long Island teens in the VIP. Lyor Cohen was also in attendance. In person he looks like Maer Roshan a bit.

Just walked past a tall Cameron Diaz crossing 6th Ave at 53rd around 1:30 today (5/3/05). She was with two non-descript dudes and a gaggle of teenage fans following 50 feet away. Cameron was fresh faced, keeping her striking blue eyes makeup free. Glanced around for JT, but he was no where in sight.

Andre3000 in SoHo, blending seamlessly into our gray urban environment thanks to a jungle camouflage outfit topped with a green safari hat. Dig.

DIANE KEATON and her daughter checking out the Max Ernst show at the Met. She was wearing a full length black north face winter jacket, black mens boots and the give away bowler hat. She was totally dressed for a snowstorm, in the 60 degree sunny weather.

At last night's Broadway Opening of Sweet Charity starring Christina Applegate, we saw Gwyneth Paltrow chatting with Adam Duritz of Counting Crows during intermission. Blythe Danner was Gwenyth's date. Just before the curtain went up for Act I, Donald and Melania Trump entered and the house viritually silenced to stare at them. Yeah, we're all still 12. Also there - Alec Baldwin, Marc Shaiman and Scott Wittman, Rosie O'Donnell, and probably a bunch of other people I couldn't name. I guess Christina is a bit of a draw.

I saw the infamous Katie Holmes riding the northbound N train in New York City on Sunday the 24th. I was hawking shirts for charity/a competition (terrible) and she dug into her purse and gave me a crumpled ten dollar bill. Big sunglasses, cute sweater, cute flats. She didn't want a tshirt so we gave her a button. I said "thank you" again to get her to speak/smile, and I definitely thought it was her. News broke a day or two later; was Sunday the 24th too late for her to be in New York and not Rome?

Saw Michael Stipe having a drink with a friend at Shag, on 8th Ave between Bleecker and W. 12th yesterday (5/02) around 6 pm. He was all relaxed and gaunt and was wearing a maroon hoodie. He paid with an American Express, but not the black one. It read J. Michael Stipe on it.

On Saturday 4/30, during the Revlon Run/Walk for Women through Central Park, saw Law & Order: SVU's Mariska Hargitay, who was a participant. She was walking with some friends, and seemed happy and was very friendly to everyone around her despite the rain and the random people who kept asking her where Detective Stabler was. Also, she's one of those famous people who is quite beautiful in person, despite a lack of makeup and the soggy weather.

Leaving Citrus on Saturday evening when I looked up and saw he-of-the skinny-tie / drainpipe jeans / afro, uber-hip guitarist Albert Hammond (Jr.) of The Strokes. Looks exactly like he does in every picture ever taken of him, outfit wise. His party was waiting for their table, and upon further inspection, revealed another member of recognition: Fab 5 Freddie. He was rockin' the dark sunglasses and stylish threads, and I immediately altered this assessment in my mind and took note that I would henceforth think of it as Fab 5 Freddie's party, waiting for a table. They must have just gotten out of the Beacon, where Dylan was playing that evening.

Sat at the table across from Karolina Kurkova's 8 pm Friday night (4/29) at Woo Lae Oak in SoHo. Blond hair in a ponytail and surprisingly not as tall as I thought she would be. She was with a not very attractive guy in his 30's or so.

Paris Hilton was at Koi eating (or pretending to eat) dinner on Friday Night.

I was at this TAA (thought is was t & a since when i read the sign that the playboy foundation was hosting) awards at the Tribeca Grand. I saw Veronica Webb, Rosie Perez, Mick Rock, Jane Rosenthal and none other than the desperate housewife herself, Teri Hatcher not looking too desperate. She looked rather occupied with a youngish looking bearded man.

foxy brown at the times square jamba juice 1130ishpm, saturday, april 30 didn't realize it as her until after she'd left when some girl an after her to get her autograph. is a total b! thought she was a drunk tourist, she was so obnoxious. wouldnt look at the menu to order, shouted she wanted strawberries and bananas, but not the one on the menu that was strawberries and bananas; also to make it real thick. paid with change. drove off in a silver rangerover.

A sighting worthy of all those Star Warophiles lined up outside the Mann Theater in LA, on Thursday the 28th, my girlfriends and I saw the original Darth Vader himself (James Earl Jones) at La Guardia going through airport security. He didn't want (or have) any special treatment, and his carry-on luggage was apparently clear of light sabers. He definitely did not want any attention and was not thrilled when the security guard who was about to frisk him complimented him 'on his work'. At least at that point we were blessed with hearing that famous voice, although he never uttered the phrase "Luke, I am your father". Sorry.

Saw the one and only, blue lagoonish, Amazonian, Brooke Shields getting ready to attend some function in that function space on 20th street (I think) between sixth and seventh avenue. She looked just how she should at her age, not botoxed up or anything. Quite lovely and as tall as a damn skyscraper!

Last week, I got to meet Kelly Osbourne at a party thrown by Paper Magazine for the documentary about the vile Glenn O'Brien's "TV Party" (a public access show back in the 80's) at the Tribeca Film Festival. Kelly O made eye contact with my boyfriend and introduced herself. She seemed surprisingly shy and was very nice. She is actually very pretty and not chubby at all—-she just has a round face and her bazoombas are huge!!! In any case, she left early on, hanging out with Richie Rich, Traver Rains, and Aimee Phillips of Heatherette and DJ Michael Cavadias. Later that night, I saw Fab Five Freddy from that really old MTV hiphop show back in the 80's and Debbie Harry sang something that was unintelligible and that she read from a piece of paper.

I saw Lorne Michaels at one of the Friday shows for "Family Guy Live!". He was with a whole bunch of kids; I guess they were his grandchildren.

Saw Dennis Quaid outside of Balthazar last night. He seems to grow hotter by the day. Meg Ryan is an idiot.

Walking home yesterday on Perry Street and saw the gorgeous Julianne Moore and her...is it husband - i really need to study Star more...he was hugging her, she was smiling - was way sweet.

Saw Marcia Cross walking on up 5th Avenue (near 57th St) yesterday (May 3) around 1:30pm. I first noticed her because of her beautiful hair- the color is sick and she had it down. She was wearing normal jeans and a long velvet maroon coat- it looked vintage. She was very cool and seemed to not be bothered at all by every person on the street noticing her and saying "Oh my God, Desperate Housewives!". Her skin is beautiful- great body and very cool. I was temped to say "I loved you on Melrose"- but refrained. I think she was going to Bergdorfs...

Saw Hugh Jackman yesterday (5/3) sitting on the corner of 57th and 5th looking delish with a kid in his lap (his, I'm assuming) and as I passed by some blond lady came over and kissed him on the lips. Lucky gal. Earlier in the day saw Jeff Goldblum coming out of the Flatotel on 52nd Street and opening the door to a Lincoln towncar to ask if it was his ride. Not as tall as I would have expected, though.

Wednesday about 9:30am, Fish himself, Abe Vigoda, was stepping out of Lenny's restaurant on 2nd Ave on the Upper East Side w. a tray of breakfast and coffee, trying to determine which one of the numerous open outdoor tables he and a companion would sit at. He was his usual tall, dour-faced, slouching self. He looked old, but then again, he IS old. Some Gawkers will think of Vigoda always as Tessio from the Godfather. Youngn's will just know him as the old guy who does cameos on Conan O'Brien. But to me, he'll always be Sgt. Fish from Barney Miller.

just saw kerri russell on park ave south near union square. She was wearing a jean jacket and jeans made of the same material! Tsk tsk. regardless, she looked petite and precious.

I saw Monica Lewinsky at Sway on Spring Street a couple of nights ago talking to the editor in chief of Heeb magazine. She looked like Ricki Lake in Hairspray, lots of hair and hips. Does this sighting even count? Is she even a real celebrity anymore? [Ed: As long as she blew President Clinton, yes.] She's a "handbag designer," the same fake profession as Nicky Hilton.

Just saw Paul Rudd walking a massive white dog near the dog run in Washington Square Park. The dog had some very impressive slobber hanging out the sides of its mouth, as did I. He'c cuter than I remember.

Opened the door for Oprah's BFF, Gayle King, on 43rd & 2nd. She thanked me with a warm smile. Didn't get the chance to ask about Stedman's penis size.

On Sunday 5/1 near W. 4th and w. 10th saw Harvey Keitel and family; looked like he was w/wife & son and someone else. Then, thirty seconds later, a voice comes out of nowhere that makes me swoon. Jon Stewart (again, w/wife & child) was (I think) walking out of Westville. He's not as short as everyone seems to think. Cute family.

May 1st, saw FoodTV's Alton Brown at the Met with wife and kid, in the Max Ernst exhibit. From the look on his face, he didnt seem to think that the surrealist paintings and collages were "Good Eats ".

at shade bar on 3rd and sullivan around 4 a.m. last night (5/03), dave attell was identified making out with some girl up against the window. a friend ran out to say hi, he came in, bought us a round of shots, and promptly escorted his wasted date out. thanks dave! also, a friend spotted alanis morissette on 3rd street this morning (5/04).

Almost literally ran right into Chris Parnell, of SNL/ "Anchorman" fame, in front of the Best Buy on 23rd Street on Thursday afternoon. He was on his cell phone and wearing an adorable striped polo shirt.

yesterday (5/1) saw steve from sex in the city aka david eigenberg on 6th and 19th, squatting under a phone booth on a cell phone (???) wearing dirty jeans and a tee. I'm ashamed to say that not even my Olsen-twin sunglasses (read: enormous/hide half my face) hid my gawking eyes and open jaw.

Spotted with the cutest babyface and the sexiest lips this side of...Lisa Rinna (?) was John Legend on 1st Avenue downtown on Sunday night. I've heard rumors of his diggin' the fellas, thus my very gay decision two blocks later to turn around and walk straight back to where I saw him in the first place. Alas, Legend was long gone.

Imported domestic goddess RACHEL ASHWELL looking quite Shabby and not so Chic in SoHo on a rainy Saturday afternoon. She's still working that all-white "spiritually pure" fashion look. It must be a bitch being spiritually pure when stepping over mud puddle and avoiding splashes from taxis.

Saw Lizzie Grubman and Kelly Osbourne at the House of Wax premiere on Saturday night/Sunday morning. Kelly was clinging to Lizzie (as if she desperately wanted to be the newest PoweR Girl), and then, upon seeing Elisha Cuthbert, started screaming, "Elisha, Elisha!" Guess she's a fan.

I saw Derek Blasberg as he chain smoked cigarettes with Stefano Pilati from YSL and Marc Jacobs (both of whom are rather attractive, if I may say so) outside of the Mercer Hotel. I decided to sit on the bench outside and sip my mixed juices, mulling over a completed day of stalkings. But I was wrong. Just then, I was bombarded: Karl Lagerfeld breezed by with a flurry of busy-looking assistants, and then Jake Gyllenaal and Jimmy Fallon wobbled out of the hotel with two unknown young women. No Kirsten in sight though, thank god.

ellen pompeo at marc jacobs on bleecker street sunday afternoon. her skin resembled her character's name.
