• Mischa Barton didn't do so hot while filming scenes for Law & Order: SVU earlier this week. She reportedly forgot her lines repeatedly and some people suspect it's because the troubled actress has been partying a bit too hard recently. Then again, after playing a strung-out hooker on L&O, her career has nowhere to go but up, right? [NYDN]
• Publishing heiress Lydia Hearst has posed for Playboy and had a guest appearance on Gossip Girl. What's next? She's leaving NYC for Los Angeles to launch an acting career, naturally. Unfortunately, she's taking her boyfriend, spiky-haired pop rocker Ryan Cabrera, along for the ride, so she may not be getting off to the best start. [P6]
• Speaking of people who have built a career based on their willingness to take off their clothes, remember Amy Fisher? She'll be getting naked at a restaurant on Long Island this week and is setting aside a portion of the proceeds to help victims of the earthquake in Haiti. Your turn, Buttafuoco. [P6]
• John Edwards has finally come clean and admitted that he's the father of Rielle Hunter's two-year-old daughter. Better late than never? [People]

• The messiest TV feud in years may be nearing its end. Conan O'Brien and NBC are said to be close to signing a deal that would allow Conan to walk away from The Tonight Show with $32.5 million in hand. He wouldn't be able to host a show on another network until September under terms of the agreement. And it remains unclear if he'll be able to take some of the memorable characters he created with him, like Triumph the Insult Comic Dog or the Masturbating Bear. [TMZ]
• Has Jennifer Aniston finally found love? Probably not, but she's reportedly hooking up with Gerard Butler again. After taking pictures together on the red carpet at the Golden Globes, Aniston and Butler were supposedly seen "making out" backstage and were "attached at the hip all night." [P6]
• Madonna may be looking to add to her collection of kids. According to a Brit tabloid, the 51-year-old singer wants to have a baby with her Brazilian boytoy Jesus Luz since she has "endless love in her heart for another child." [Sun]
• Tiger Woods may be staying at Pine Grove, a sex rehab facility in Mississippi, if you happen to be looking for him, or you just need the name of a place that will treat your own compulsion to sleep with hookers and waitresses. [Us]

• Remember the dust-up a couple of weeks ago when it was reported that Beyoncé had performed for the son of Libyan dictator Moammar Khadafi in St. Bart's on New Year's Eve? Photos of the concert have now surfaced, although the worst thing about them may be how Beyoncé looks like she's the headliner at a tacky club in New Jersey. [DM]
• Is Bethenny Frankel trying to pull a Star Jones? It seems Frankel has been approaching vendors and asking them to "sponsor" her wedding: She'd get their services gratis and, in exchange, they'd get a mention on her upcoming reality show, Bethenny's Getting Married. The only problem with Bethenny's grand scheme? She hasn't had much luck finding companies interested in taking part. [NYDN]
• Here's a great idea: David Letterman has reportedly invited Conan O'Brien to appear as a guest on his show. Cross your fingers! [PopEater]
• Justin Timberlake and Jessica Biel have not broken up, in case you were concerned. According to friends, he'd committed to working on a film in Wyoming, which is is why he didn't climb Mt. Kilimanjaro alongside Biel. It's not because he didn't want to, say, spend a week living with the love of his life in a tent. He would have totally done it if he could have. Really. [P6]
• Brad Pitt and Angelina Jolie donated $1 million yesterday to Doctors Without Borders to fund emergency medical operations in Haiti. As for whether Tiger Woods really paid to send a plane full of medical supplies to the devastated nation, that's a (pretty unlikely) story that Russell Simmons has been circulating, though Tiger's reps have yet to confirm it. But it wouldn't be the worst way to begin rebuilding his image, come to think of it. [Us, TMZ]

• A-Rod dumpee Kate Hudson was "consoled" by fellow Rodriguez ex Madonna at the premiere of Nine on Tuesday night. As for A-Rod, he was spotted in Miami yesterday, where he supposedly made the moves on a blonde at a restaurant but came up short. There's hope for A-Rod and Kate yet, though. The two have reportedly been speaking on the phone this week, and Hudson is still hoping they can patch things up. [P6, NYDN]
• A car that Anne Hathaway was riding in struck a cyclist in LA yesterday. Thankfully, Anne emerged unscathed. But ever the good girl, she hopped out of the car to tend to the biker and was photographed looking concerned. [TMZ, People]
• Today in Tiger: Elin Nordegren has supposedly made up her mind that she's leaving him, and has been shopping for divorce attorneys before she plans to head to Sweden for Christmas; Woods' high school girlfriend is now blaming the whole mess on Tiger's father, who may have been a serial cheater; Jessica Simpson is denying reports she ever hooked up with the golfer; and as for Tiger himself, he's supposedly spent the past few days holed up at home where he spends his time eating cereal, watching cartoons, and feeling depressed.

Brad goes out of town and Angie flies into a depressive rage, Madonna's face is bloated (with restylane?), Anne Hathaway is in a car crash with a stylish cyclist. Thursday's gossip is full of peril.

• A "bone-thin" Elin Nordegren moved a big bunch of belongings out of the Florida mansion she shares (shared?) with Tiger Woods yesterday; she's supposedly headed "somewhere warm" for Christmas. As for Tiger, it seems he's going to spend Christmas with "the boys." Maybe Rachel Uchitel will stop by for a visit? According to tabloid reports, Tiger is still in contact with Mistress No. 1, and is hoping to squeeze a little time to get together. [NYP, NYDN, People, Us]
• Lindsay Lohan may have to put off any more trips to rescue exploited children living in Third World countries. A judge has ordered her to start attending her alcohol education program classes "every single week" because, well, "it's been long enough." [Us]
• Why did Alex Rodriguez and Kate Hudson break up? According to a highly dubious story that one of the slugger's pals has been telling the tabloids, it was because Hudson wanted to be on camera when she sat in the stands at Yankee Stadium, whereas A-Rod really wanted someone "more interested in building a long-term relationship than just building their profile." [Us]
• As for Hudson, she's dealing with the split from A-Rod by spending some quality time with her movie star parents, Goldie Hawn and Kurt Russell. Goldie turned up as Kate's date to the Nine premiere last night. [HL, DM]

Tonight, NBC premiered The Sing-off—a four-day a cappella group competition that was marketed as a cross between American Idol and Glee—and it was amazing, for all the wrong reasons. Here are the six things I learned while watching.

A newly unengaged Uma Thurman heading into an office building (and avoiding questions by waiting paparazzi) ... Ashlee Simpson and Pete Wentz walking downtown with their son Bronx ... Sienna Miller hailing a cab downtown ... Jessica Szohr walking to the Gossip Girl set on Central Park West ... Naomi Watts pushing son Sasha in his stroller in SoHo ... Kim Kardashian arriving at Fox News ... Jessica Simpson leaving the Ritz-Carlton with Billy Corgan ... Chris Brown leaving MTV ... and Taylor Swift walking into Otto to have dinner.

The Smashing Pumpkins frontman can now add Jessica Simpson as another notch in his rather unfortunate bedpost. Billy, it's time to stop dating below you and get back to work doing something great. We have suggestions.

Rihanna attending last night's Knicks game at Madison Square Garden ... Kate Hudson walking downtown with her son Ryder ... Jude Law leaving his apartment in the Village on Sunday afternoon ...

Natalie Portman filming scenes for her new movie ... Blake Lively heading to the set of Gossip Girl with a bodyguard yesterday ... Sienna Miller walking her dog downtown ... and Eva Longoria leaving the Ethel Barrymore Theater after attending the opening night of Race.

• Although Tiger Woods and his wife remain "in seclusion" at their home in Florida (and are supposedly involved in "intense" marital counseling sessions), their lawyers are still ironing out a revised pre-nup. One report suggests Woods would pay his wife $5 million immediately and then $55 million if she stays with him for another two years; all she'd have to do is suck up any semblance of pride and sign a nondisclosure agreement. Meanwhile, sources indicate that Tiger was working on a deal to pay Rachel Uchitel $1 million to keep her trap shut, she hasn't taken any money from him (yet), and canceled her press conference yesterday because she was "scared for her safety." What else do we know? That Tiger is painfully insecure about his tiny calves, for one thing.
• In an interview with Glamour, Sarah Jessica Parker says she has "enormous regrets" about filming the Sex and the City sequel since because she didn't want to miss being home with her two baby daughters for one moment. Let's all hope the millions she makes from the movie more than makes up for it. [Us]
• Is 15-year-old Tallulah Willis (daughter of Bruce Willis and Demi Moore) dating 16-year-old Patrick Schwarzenegger (son of Arnold and Maria)? Possibly, although Bruce's rep is now denying it. [P6]
