• Mischa Barton didn't get involuntarily committed to the psychiatric wing of Cedars-Sinai last month because she had a meltdown. Or a drug problem. She says it was because she had her wisdom teeth removed. Sounds plausible! [TONY]
• Speaking of lame excuses, remember how Jeremy Piven said he had to drop out of Speed the Plow because he had mercury poisoning? An arbitrator bought the story, apparently, because he ruled in his favor, dismissing charges filed against him by producers of the show. [NYP]
• Minka Kelly's rep is shooting down rumors that she's planning a fall wedding to Derek Jeter. [NYDN]

• Is Kate Middleton, Prince William's girlfriend, planning to move to New York? Possibly! [DM]
• A coroner has ruled Michael Jackson's death was due to lethal levels of the anesthetic Propofol in his body, which may very well pave the way for prosecutors to file manslaughter charges against Jackson's doctor, Conrad Murray. [MSNBC, People, NYDN]
• In other Jackson family news, Barbara Walters has landed the first interview with LaToya Jackson, which will air on September 11. Exciting, huh? [ABC]
• Jessica Biel is the most dangerous celebrity on earth—at least when it comes to computer viruses. People who seek out info on Biel online stand a one-in-five chance of visiting a site "designed to damage their computer." [Us]

Melanie Griffith's drying out, an Amy Winehouse love letter sparks a lawsuit and Robin Williams may channel Susan Boyle. That — and more — in your Tuesday morning Gossip Roundup. Delicious!

Speidi acts the ass at the Miss Universe pageant, Sting's status as a sexual God is bullshit, Kim Kardashian and Reggie Bush reconcile, Jason Schwartzman got married, Marc Jacobs is getting married, and Amy Winehouse goes on a 48-hour bender.

• One of Jay-Z's bodyguards was arrested in Croatia yesterday after he got into a scuffle with a local TV reporter armed with a tripod. Video of the encounter is here. [TMZ]
• Heidi Pratt is scheduled to perform at the Miss Universe Pageant this weekend; not surprisingly, she and husband Spencer Pratt haven't exactly been making things easy for organizers of the event. [P6]
• Is it over between Renee Zellweger and Bradley Cooper? The two didn't attend the party for Zellweger's new movie together and, well, we all know what that means, don't we? [P6]
• Rudy Giuliani wandered into Blue & Cream in East Hampton the other day because he thought the clothing boutique was an ice cream shop. [P6]

• Olympic swimmer Michael Phelps got into a car accident in Baltimore last night, but there were no serious injuries reported. [NYDN]

• Don't be surprised if you hear Mischa Barton's checked herself into the hospital again. She's been out, oh, two weeks now and the British tabloids are focusing on all the cellulite she has, poor thing. [DM]
• Heidi Pratt says she has "20-30 orgasms per day" with husband Spencer Pratt. Could this be because she experiences what she thinks is an orgasm every time she sees her name appear in tabloid or gossip outlet? Just an idea. [P6]

• The case of the mercury-tainted sushi lives on: Chris Kattan ran into Jeremy Piven backstage during a taping of Alexa Chung's MTV show last week and made a crack about Piven's short stint on Broadway; a very offended Piven responded by calling Kattan's entire career into question. [NYDN]
• Madonna's Brazilian-born boy toy, Jesus Luz, is more than just a model: He's now a DJ, too. [P6]
• Bethenny Frankel is no fan of Gwyneth Paltrow: "I'd rather staple my eyelids shut than watch Gwyneth cook." We're going to assume the feeling is mutual. [NYDN]
• In what amounted to a two-way publicity stunt, Kathy Griffin and Levi Johnston (better known as Bristol Palin's baby daddy) turned up to the Teen Choice Awards last night holding hands. [Us]

• Madonna is taking her kids on the best summer vacation ever later this month: She's thinking about taking them to visit Auschwitz, so "they can learn about mistakes made in the past." If that doesn't pan out, she could always just invite Sean Penn and Guy Ritchie over for a visit and teach them the same lesson, couldn't she? [YNET]
• Paula Abdul announced over Twitter last night that she's leaving American Idol. True? Was she just drinking again? We'll find out soon enough. [NYDN]
• Hopeless romantic Kelly Bensimon made a move on Gerard Butler the other night, but the actor didn't reciprocate. Try your best to empathize. [NYDN]

Queen Latifah riding a bike in Central Park for her new movie, Just Wright ... Rihanna leaving an office building in Tribeca ... Hugh Dancy walking into MTV Studios on Times Square ... and Leighton Meester going to see Katy Perry perform at the Hammerstein Ballroom with boyfriend Sebastian Stan.

• Jude Law's rep says that the actor recently found out that he's expecting a fourth child. The mom? She's "an unidentified former lover." Congrats? [EW, People]
• It was less than two weeks ago that Mischa Barton was put under psychiatric care after she going on a drug-fueled bender and suffering a breakdown. Now she's in NYC, putting in long hours playing a character with a drug problem. Maybe this isn't the best idea? [NYDN]

Amy Winehouse reached into Kate Moss' handbag and stole her cocaine, Kim Kardashian and Reggie Bush break up, Madonna's love faxes from the early 90s emerge, Tobey Maguire's mom and brother get a reality show and Mischa Barton goes home.

• Remember when Bethenny Frankel announced a few weeks ago that she was engaged to "a real estate bigwig" named Jason Hoppy? According to one "insider," the engagement may be a big publicity stunt, and Hoppy may be a "medical sales rep/personal trainer," not some property-owning master of the universe. [Fox News]
• A treasure trove of Madonna memorabilia, collected by one of her long lost ex-boyfriends, is going up for auction. Yes, 17 minutes of "erotic phone messages" could soon be yours. [P6, NYDN]
• Kim Kardashian and Reggie Bush have broken up. Tragic! [People]
• It looks like Dr. Conrad Murray gave Michael Jackson a dose of the powerful anesthetic propofol right before his death and that was what killed him. And it looks like Murray could face manslaughter charges because of it. [TMZ, NYDN]
• Mischa Baron says she's feeling better and is ready to go back to work. [Us]

• The police were called to Mischa Barton's home yesterday and she was escorted out of the house so she could be treated for some sort of "medical issue." Her condition hasn't been disclosed yet, but we're going to go ahead and assume it wasn't a case of seasonal allergies. [Sun]
• Bethenny Frankel may be giving up her spot on the Real Housewives next season so she can star in a Bravo show of her own. Neither Frankel and Bravo were willing to confirm the news, though, so we're going to keep our fingers crossed and hope this is just a crazy rumor that has no basis in reality, okay? [P6]
• Kim Kardashian almost got stranded in Africa when she couldn't locate her passport. The operative word there is "almost": Sadly, boyfriend Reggie Bush found it a few minutes later, so she was able to return to the U.S. [People]

Did you know that Kim Kardashian is in Botswana at the moment? (That's the country in Africa named Botswana, by the way, in case you were thinking it might be some new jungle-themed club in LA.) What could possibly explain Kardashian's decision to travel to such a poor African country? Diamonds, of course! Kim and boyfriend Reggie Bush made the trip as "representatives" of Russell Simmons' Diamond Empowerment Fund, a foundation backed by companies like DeBeers that assists "economically disadvantaged people in African nations where diamonds are a natural resource." But DeBeers & Co. is totally getting its money (or diamonds') worth. Kardashian is learning all sorts of interesting things about the economy of Africa, and she's sharing her newfound knowledge on Twitter: "Did u know that 75% of Botswana's economy is supported by diamonds?" Actually, we didn't. But now we do! We fully expect to see Kim talking economics with Jeffrey Sachs when she gets back to the States. In the meantime, you'll find a few more of Kardashian's revelations—opposite a photo of Kim in a bikini, weirdly—below.

And you thought PC Peterson lived a charmed existence. It seems things did not go well for the NYC Prep castmember when he turned up at last night's launch party for Three-O vodka, hosted by Kim Kardashian: "Jessie and PC from the show turned up and tried in vain to join their friend Ally Zarin from The Real Housewives of New York inside. Publicists refused to let them in because they were underage—even though Zarin, who also is not yet 21, was partying away inside." [Daily Intel]

Rumors of the Goldblum/Ford deaths were greatly exaggerated, David Gregory throws a hissy over Joe Scarborough, Kate Gosselin sports a bikini in the driveway, Kim Kardashian lusts for Megan Fox and Chris Brown and Rihanna want to touch.

• Here's a rather unlikely rumor but an amusing one all the same: Prince William is supposedly thinking of moving to America with his girlfriend, Kate Middleton, and the two have been spotted house-hunting in Malibu. Frankly, if they were going to move to America—and they're probably not—we see them as more of a New York couple. And NYC could use a prince roaming around, couldn't it? Let's all cross our fingers and hope for the best. [E!]
• Countess (and not-so-real housewife) LuAnn de Lesseps was spotted hanging out with young men and doing tequila shots at a club in the Hamptons last weekend. And the earth continues to rotate on its own axis, too. [P6]
• That was quick. Just a couple of weeks after Lindsay Lohan and Sam Ronson supposedly reunited, the couple appears to have split up again—and it's all Nicole Richie's fault, too. Or maybe they never got back together at all? Feel free to take your pick. [E!, People, AH]

Ashlee Simpson got drunk at a party and made a spectacle of herself by screaming at Pete Wentz's ex Michelle Trachtenberg, Brad Pitt shares hygiene secrets, Kim Kardashian and Reggie Bush marriage rumors swirl, and Chris Pine dumped Audrina Patridge.
