Did Vince Vaughn re-enact parts of his frat boy comedy "Old School" shortly before he and Jennifer Aniston induced a collective yawn by announcing they had "mutually agreed to end their relationship"? Us Weekly reports the baggy-eyed funnyman, who's been in London for the last few months shooting "Fred Claus," spent Thanksgiving weekend enjoying the many delights Hungary has to offer, whooping it up on Nov. 24 with two pals at a gentlemen's club in Budapest called Moulin Rouge. "It's a dressed-up [rhymes with 'kitty'] bar," a "local" tells the magazine. "The girls get pretty wild in there ..." Us says the party later moved to a techno club, where Vaughn purportedly plied his charms with "several" female admirers. "He wasn't there to dance," maintains an eyewitness. "It's a meat market." Meanwhile, Star is atwitter with talk of the actor's alleged close encounter the following night with a 20-year-old Texas sorority girl, who supposedly detailed the rendezvous in a gushing e-mail sent to 22 of her sisters titled, "I shacked with Vince Vaughn." Among the highlights, as excerpted by the tab: "... next thing I know it was me and Vince Vaughn alone in the hotel room. For a while we just had a drink and talked some more (and yes, we talked about Jen) and one thing led to another ..." And while there was no real naughtiness, just some "messing around," she still "felt like I was in a movie. We didn't ever go to sleep and in the morning he walked me out and kissed me goodbye in front of everyone and was so sweet."

Rosie O'Donnell has barely had time to form a nice butt groove in the couch on "The View" and already rumors are flying that she's considering packing it in. "Rosie could be gone within six months," a mole tells the New York Daily News. "She's grown tired of the daily dramas with her co-hosts and the crew. She wants to spend more time with her family." The insider claims the atmosphere on the set has grown contentious, with Barbara Walters, Joy Behar and Elisabeth Hasselbeck tired of being unable to get a word in edgewise. "She's turned it into her show," huffs the mole. "The others resent it. But if she goes, they'll play it as a 'mutual decision.'" Not so, says O'Donnell's rep, who insists to the paper, "Rosie is having a great time. Everyone is getting along. She's gone out to dinner and to the theater with Elisabeth. And she and Joy have been friends for over 20 years. There's no animosity."

We always figured Oprah Winfrey was a lot like the Hulk -- you really wouldn't like her when she's angry. Tom Cruise, however, seems unafraid of incurring the wrath of the all-powerful O. The New York Daily News reports Oprah has once again failed to score an invitation to celebrate the onetime sofa stomper locking down Katie Holmes as his third wife. The PR-courting pair is planning a postnuptial soiree this weekend at the L.A. home of Tom's producing partner, Paula Wagner, reportedly for those who couldn't make it to their multimillion-dollar, paparazzi-crammed "I do" extravaganza in Italy last month. But it looks like the party has already begun. On Wednesday night, Tom and Katie dug into a steak dinner with wedding guests Victoria Beckham, Jennifer Lopez and Marc Anthony at Wolfgang Puck's eatery The Cut in L.A.

Don't hate Ellen Pompeo just because she has zero body fat. "If I could gain 5 to 10 pounds, it would probably go straight to my boobs and a**. I would be the happiest girl in Hollywood, trust me," the angular "Grey Anatomy" actress tells Playboy (via the New York Post). "I'd have this sick bod because I'd be the skinny girl with big boobs and a cute butt."
