• Lady Gaga collapsed in her dressing room last night just before she was set to perform at Purdue University. Paramedics were called and she reported she was "feeling dizzy and having trouble breathing," and the concert had to be canceled. But she's okay today and has since apologized to her "little monsters" (fans) on Twitter, so everything is cool now. [Sun, MTV]
• Lindsay Lohan hung out with Jersey Shore's Paul "DJ Pauly D" Devecchio and Mike "The Situation" Sorrentino at a club in LA the other night. If you, too, want to fist-pump with Pauly, you can: He'll be DJing at a Midtown baron Jan. 23, and the cover is only $10. [Us, NYP]
• George Clooney is hosting a telethon next week to raise funds for Haiti. Other celebs pitching in to help: Gisele Bundchen has pledged $1.5 million with husband Tom Brady; Madonna says she's good for $250K; and David Blaine is performing for three days in Times Square as part of a fundraiser for the Red Cross. [Us, NYDN, People]

Thanks to the informant, she recently broke up a date between hubby and a young PA. Another actor shouldn't be trusted and stole jewelry from his ex to regift and a paparazzi is in love with a star. Oh, boys.

• 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]

One partner gets a beard, the other gets money for drugs and gambling. They're still married, just like this comedian who never got his drunk Vegas marriage annulled and now can't marry his famous girlfriend. Matches made in heaven!

• Those rumors about Tiger Woods in rehab have returned. According to People, Woods checked into a sex rehab clinic around New Year's and will be there until "Valentine's Day or thereabouts." (Perfect timing!) As for his estranged wife, Elin Nordegren, she's moved into a new home that's just a couple of miles from the gated community where she used to live with Woods. [People, TMZ, NYDN]
• Have Justin Timberlake and Jessica Biel split up? That's what some people are saying, since she spent the last week climbing Mt. Kilimanjaro while he was in Jackson Hole, Wyoming. And couples that are really in love would never spend a moment apart, would they? Didn't think so. [Radar]
• The Post reported a few days ago that Derek Jeter and Minka Kelly have made plans to get married in November. Naturally, this had led the Daily News to report today that the story is totally untrue and the couple hasn't even discussed getting engaged, at least according to one of Minka's friends. [NYDN]
• Forbes released its list of Hollywood's "top-earning couples" yesterday. The winner? That would be Beyoncé and Jay-Z, who reeled in $122 million last year, or more than double what Angelina Jolie and Brad Pitt collected. Possibly related: Beyoncé said yesterday that she plans to take a "hiatus" from singing so she can "live life." Which is what you'd do, too, if you made nine figures over the last 12 months. [Forbes, NYDN]
• The Conan-Leno mess is bad news for NBC. But it's also made late-night TV sorta watchable again, which is nice. [Gawker]

Casey Johnson was buried in New Jersey earlier today. As you could have guessed, Tila Tequila wasn't invited to attend the private service. But that's probably just as well since she's been busy today launching her own record label. [NYDN]

We blame Drew Barrymore for creating the very-young-starlet-on-drugs archetype. It's being recreated by this girl, who is also bedding two older men. She shouldn't get advice from this actor, who is a sloppy drunk. Back on the wagon, everyone.

• This is going to come as a big shock to you, we're sure, but it seems Alex Rodriguez has been hooking up with several women since splitting up with Kate Hudson. A-Rod also "keeps bragging that Madonna is still texting him all the time," although for Madonna's sake, let's hope that isn't true. [P6]
• Angelina Jolie has been dropped as the face of the clothing brand St. John in favor of red-headed model (and the wife of Jack White) Karen Elson. Why the change? It seems St. John concluded that Jolie was too famous and had "overshadowed the brand." [NYDN]
• Related: Did Brad Pitt deal weed in college? No, but he kind of looks like he may have what with that scraggly beard he's been sporting recently. [NYP]
• Usher had more than $1 million in jewelry, furs, and electronics stolen from his SUV in mid-December. Exactly why he had all this stuff stored in his car of all places—and why he only noticed now—is unclear. [TMZ]
• Tila Tequila was set to be interviewed on Larry King Live, but CNN yanked the "Casey Johnson tribute" at the last minute. Did the network realize giving a mentally-ill publicity addict was a bad idea? (Unlikely; the Balloon Boy dad was a guest the other night.) Maybe CNN worried about getting sued? Who knows, but you can always go to Twitter (where she's tweeted about Johnson's death more than 160 times over the past week), or go to People's website for your "Tila Tequila exclusive interview," if you must. [TMZ, E!, People]

This jock thinks it's a turn-on to tell ladies he eats his ejaculate. Classy! The porn star that this actress wants to play on screen did the same, and maybe a smarmy record exec does too. It's an all-you-can-eat buffet.

After getting some coffee milkshake at The Coffee Bean, Miley gets her Prius' mixed up (a common mistake), and a throng of photographers guide her in the right direction. What would humanity do without the help of the altruistic paparazzi?

• A photographer says he plans to file a lawsuit against Lindsay Lohan after her driver "nearly killed" him in a hit-and-run accident on Sunday. The paparazzo says he's "lucky to be alive" and now plans to make sure Lindsay "goes to jail" for her crimes despite the fact LiLo wasn't even the one driving, and the photographer only injured his wrist and never even had to go to the hospital. [TMZ, NYP]
• Have Derek Jeter and Minka Kelly set a date? According to the Post, which conducted an undercover investigation last week, the couple are planning to get married in November at the Oheka Castle on Long Island, which is where Kevin Jonas got married recently. [NYP]
• Another Beyoncé concert is stirring up controversy. Less than two weeks after she got into trouble for performing for Hannibal Khadafy comes the news that residents of Trinidad are up in arms over a $1 million Beyoncé concert planned for February 18. Locals claim it will divert from the country's annual Carnival celebration. [Sun]

David Patrick Columbia, beloved confidante to heiresses and socialites and proprietor of New York Social Diary, would like the media to get a few things straight about Casey Johnson. He also knows all about Casey's final days, the details of which he shared today on his website. It's compelling stuff:

He's none too happy about it. It's the oldest trick in the book, but she won't be happy if she hangs with this band of terrorist Hollywood mommies or a tormenting actress. It really is cruel to be kind.

• Gwyneth Paltrow got into a minor car crash on the icy streets of London the other day. Don't worry—she wasn't hurt fine—although she may want to reconsider that all-juice "fast" she started at the beginning of the new year. [DM]
• The little girl that Casey Johnson adopted a few years ago, Ava, will be raised by her mother and sisters, according to reps for the family. And the Tila Tequila's craziness continues. Yesterday, she emerged from her house to pose in a skanky outfit for photographers, and she continues to rant on about her "fiancée" on Twitter. Meanwhile, Johnson's former girlfriend, Courtenay Semel—who set Johnson's hair on fire a year ago—has been speaking out, as has Johnson's other former girlfriend—model Jasmine Lennard, who accused Johnson late last year of robbing her and leaving a used vibrator in her bed.
• The reason for Gary Coleman's recent hospitalization? He says he had "a little seizure activity" after he found out that the producers of a film he worked on recently had no plans to remove a full-frontal shot of him. [TMZ]
• Lindsay Lohan claimed the other day that one of her friends stole sketches of her new clothing collection. But now two different designers have come out to accuse LiLo of copying their designs. The president of LiLo's company says the claims are "false and have no merit or validity whatsoever." [People]

The only thing technology is good for is getting us laid. Just ask this cheating tweeter or another double-dipping actor. It can't help this marriage-minded celeb, though. Or a pill popping pop singer. Welcome to the future.

In an apparent suicide attempt, Howard Stern sidekick Artie Lange stabbed himself nine times—six "hesitation wounds" and three "deep plunges"—and is now in the hospital. There is something extra-tragic about comedians with depression. [P6]

• The Casey Johnson saga continues: Yesterday, Nicky Hilton and Bijou Phillips, both of whom were pals of the late heiress, showed up at Tila Tequila's house to take possession of Casey's two dogs. A screaming fight ensued, and the police had to be called in to mediate, since Tequila claimed the two women were taking away the canines to be euthanized. There's some bizarre video of Tila acting crazy, if you're interested. [NYP, NYDN, TMZ]
• Peter Orzsag, the seemingly straight-laced White House budget director (and the owner of the worst toupee in Washington), has been hiding a little secret. It seems he got engaged to ABC News correspondent Bianna Golodryga a few weeks ago only after dumping his previous girlfriend, shipping heiress Claire Milonas, who happened to be pregnant with their baby at the time. [NYP]
• Speaking of embarrassing White House news, Tareq and Michaele Salahi, the fameseeking couple who crashed the state dinner back in November, will be collecting $5,000 to host a party at a Las Vegas club next week. [P6]
• The reason Howard Stern regular, Artie Lange, was hospitalized recently: He tried to commit suicide by stabbing himself nine times. Surgeons managed to save him "despite heavy bleeding." [P6]
• Jersey Shore will be coming back for a second season—or at least that's what one of the cast members is now saying. In the meantime, the crew will continue to collect appearance fees for showing up at bars and clubs. Prices range from $3,000 to $7,500 a piece, or you could pay $30,000 for the whole bunch. And just think of all the hair gel that could buy! [NYDN]
• Lady Gaga has signed a deal with Polaroid to become the brand's "creative director and inventor of specialty products." It's a touch unclear what this will entail exactly, but she may develop "imaging products" for the company and market a line of Gaga-branded cameras and accessories. [People, NYP]

Is Tiger Woods hiding out at the Long Island mansion of Jim Dolan, the "controversy-prone CEO of Cablevision and owner of Madison Square Garden and the New York Knicks"? That's what Us Weekly reported this morning, although reps for Dolan have called the story "preposterous." [Us]

Sleeping with her drug dealer was the only way to get him to forget about the money she owes him. The "next Casey Johnson" in L.A.'s socialite set hasn't sunk that low—yet. And finally, a star does something kind!
