• Eliot and Silda Spitzer made their first public appearance together last night. The couple turned up at the Waldorf for the eighth annual Children's Benefit Gala and were spotted holding hands and making "lovey-dovey looks at each other." Unconditional love is a beautiful thing. [NYDN]
• The stress over the Kiefer Sutherland/Jack McCollough incident must be getting to Brooke Shields: She was spotted looking "upset, overwhelmed and stressed" at the Innocence Project gala on Wednesday night. On a related note, the desk appearance ticket Kiefer received yesterday means he will be a free man until he shows up in court on June 21. [NYDN, NYP]
• Lindsay Lohan's 15-year-old sister Ali has reportedly dropped out of high school so she can party full-time with her big sister. Good work, Dina. [P6]
• Sarah Jessica Parker and Matthew Broderick are expecting girls when their surrogate gives birth in a few weeks. [OK!]

Barbara Walters can't remember which, uh, presidents have been on The View; Oprah Winfrey can't work a BlackBerry and Jennifer Aniston can't talk to Bradley Cooper without whispers and chest-touching.

• After 16 years of marriage, Stephanie Seymour has filed for divorce from her polo-playing, art-obsessed husband, Peter Brant. And it doesn't sound like he's taking it well: The mogul reportedly changed the locks on the couple's Greenwich mansion, and is now forcing Stephanie to sleep in the maid's quarters and threatening to take custody of their three kids. The good news, at least as far as the public's concerned: From the looks of it, the split could be just as riveting as last summer's Brinkley-Cook saga. [P6]
• Kiefer Sutherland is expected to turn himself in to the NYPD today for headbutting Jack McCollough. The penalties may be stiff, too, considering he's still on probation from a 2007 DUI arrest. [NYP]
• The Malawian father of baby Mercy says he was appalled by what Madonna wore to the Costume Institute gala this week, since she should "feel ashamed in that gear." We couldn't agree more. [MSNBC]
• Lindsay Lohan spent the night at Sam Ronson's house and changed her BlackBerry messenger name to "LL loves Sam Ronson" on Tuesday, which probably means the two are getting back together. [People]

Michelle Obama was the main attraction at Time magazine's sixth annual 100 "most influential" ceremony at Lincoln Center last night. She was joined by a predictably massive group of A-listers, including Oprah, Harvey Weinstein, Mort Zuckerman, Steve Schwarzman, Jeff Bewkes, Diane Sawyer, Barbara Walters, Whoopi Goldberg, Joy Behar, Carine Roitfeld, Gayle King, Stella McCartney, Claire Danes and Hugh Dancy, Kate Hudson, Liv Tyler, Jay Leno, Lorne Michaels, Jimmy Fallon and Nancy Juvonen, Charlie Rose, David Lauren and Lauren Bush, Ann Coulter, Suze Orman, Arianna Huffington, Kate Betts, Andy Serwer, Paul Krugman, Vivi Nevo and Ziyi Zhang, Andrea Mitchell, Chris Matthews ...

• Tyra Banks took the stand to testify against accused stalker Brady Green yesterday and explained how she's had to hire a bodyguard and driver as a result of the incident. She also said she's no longer jogging outside and has been forced to hire a personal trainer, but we're pretty sure she had one of those long before Green came along. [NYDN, NYP]
• After 13 years of marriage, Sean Penn has filed for legal separation from wife Robin, news that may not come as a huge surprise given his long list of rumored paramours, including Petra Nemcova, Helena Christensen, Ines Misan, Naomi Campbell and Natalie Portman. [P6, People, Extra]
• Liev Schreiber and Naomi Watts' son, Sasha, was admitted to the hospital on Tuesday night for respiratory issues. [People]
• Madonna supposedly wants a summer house in the Hamptons. But she can't find a place willing to put up with her horse-related demands. [P6]

• Did Beyoncé really send a look-alike to stand in for her at an art museum in Vienna so she could go shopping instead? That's what many Austrians seem to think, and the museum now says it plans to issue a protest. And here we were thinking decoy body doubles were just for presidents and mafia kingpins. [AFP]
• James Gandolfini erupted at a group of paparazzi outside the Waverly Inn the other night. Fortunately—for the drama-loving masses, at least—they kept their cameras on during the episode and it was all caught on tape. [TMZ]
• Real-life roommates Chace Crawford and Ed Westwick might be splitting up, since Chace is reportedly looking for a loft of his own downtown. [P6]
• Mel Gibson and Russian singer Oksana Grigorieva made their first public appearance together last night at an X-Men screening in LA. [People]

All relationships are "complicated," Facebook: Heidi Montag can't sell pictures of her stupid re-wedding, so why bother; Miley Cyrus is sheepishly two-timing and LiLo and SamRo restored a tenuous digital connection.

• Gwyneth Paltrow's latest goal? To get Mario Batali to lose weight, apparently. She's supposedly already given him a free membership to the gym she's opening with Tracy Anderson, since he's "the only fat friend she has, and wants him to change." [P6]
• Poor Jennifer Aniston has been "holed up" in her room at the Greenwich Hotel since arriving in New York a few weeks ago, supposedly because she's terrified of "bumping into Angie" on the street. [L&S]

• In an interview with Ellen DeGeneres, Lindsay Lohan says she's "still in love" with Sam Ronson, and that their breakup "came out of nowhere." She's also lost a lot of weight, which you've probably already noticed. [OK!, People, NYDN]
• Tim Gunn says he hasn't been on a date in 26 years, but that he's okay with it because he's "very happy being alone." [NYDN]

More bad news for Kelly Bensimon. A socialite gets engaged, and an actress turns 30. Plus the requisite Jennifer Aniston sadness news and word of Madonna's continued disgraces.

• Madonna fell off a horse while riding at photographer Steven Klein's house in Bridgehampton on Saturday. She wasn't seriously injured, but don't think for a minute she's taking any blame for the spill. Her flack blamed the accident on a rogue paparazzo who jumped out of the bushes and startled the horse, although both the photographer in question and the police don't share that account. [NYDN, NYP, E!]
• Uma Thurman and Arpad Busson were rumored to be getting hitched in the Bahamas on Saturday, although there's still no word on whether any ceremony actually took place. [People, UPI]

• Rumor has it Naomi Campbell is thinking of moving to Moscow so she can be closer to boyfriend Vladislav Doronin. Say it isn't so! [DS]

• Is Lindsay Lohan heading back to rehab? That's what her mother, relatives, and friends are supposedly encouraging her to do, since she's been on a "self-destructive binge of partying, tears and breakdowns" ever since Sam Ronson broke up with her. To make matters worse, she keeps bumping into Sam everywhere she goes. Clearly, the girls need to decide once and for all which one's getting Chateau Marmont so this sort of thing stops happening. [OK!, L&S, P6]
• The Sun reports Madonna and Jesus Luz have reunited. As the story goes, Jesus came back to NYC to "perk up" Madge after all that trouble in Malawi and now they're like, going to Kabbalah classes and, like, eating dinner together and stuff. [Sun]
• Drew Barrymore and Justin Long are supposedly dating again, even though they claim they're "just friends" in public. [NYDN, P6]
• "Real Housewife" Jill Zarin recently underwent breast reduction surgery. If you're lucky, you'll see the whole procedure go down on a future episode. [P6]

There there, celebrity magazine editors: While Lindsay Lohan's rehab would slow the flow of gossip considerable, you could recoup your losses several times over with a Jennifer Aniston-David Schwimmer baby cover.
