• Lady Gaga collapsed in her dressing room last night just before she was set to perform at Purdue University.

• 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]

• A sex tape featuring Lindsay Lohan may be on the way. Actually, it's not really a sex tape. It's only 47seconds long, so it's more of a "sex clip." And it may not exist at all, according to Lohan. [DM, E!]
• Leona Lewis has had a bad string of luck lately. Just months after she was punched in the face by a fan at a book signing, she got caught up in the middle of a high-speed police chase the other day while on a Starbucks run in Los Angeles. "Thugs waving handguns ran toward her car," and her manager was accidentally knocked to the ground by police during the commotion. But Leona wasn't hurt, so that's good news. [DM]
• Erica Wang—the former fiancee of celeb chef Todd English, who allegedly beat him with a wristwatch—got off easy in court yesterday. A judge said the charges against her would be dropped if she attended six months of anger management classes, does 10 days of community service, and adheres to the restraining order against her. [NYP, NYDN]
• Tila Tequila's poor publicist quit yesterday. Naturally, that didn't slow Tequila for a second. She now says that she totally knows what caused Casey Johnson's death.

• Bar Rafaeli, the Israeli model and and off-and-on girlfriend of Leonardo DiCaprio, could be in some trouble. It seems she may have dodged Israel's draft by getting married to a friend and then divorced right after. [NYP]

• Courtney Love took to her new Twitter account (she quit her first one in October) and threatened to sue her late husband Kurt Cobain's mother and sister for custody of her daughter Frances Bean.

• Kate Gosselin hates her hair extensions and thinks they make her look like of Tiger Woods' "bimbos," a "source" tells Us Weekly. Think this story has something to do with the fact it was arch-enemy People magazine that paid for Gosselin's extensions and put her on its cover last week? [Us]
• Giuseppe "Joe" Giudice—Teresa Giudice's husband on Real Housewives of New Jersey—was charged with DUI after crashing his car into a telephone pole. [People]
