John Mayer danced on the table and chugged vodka straight from the bottle at Anchor Bar on Saturday. (He also turned down two hot blondes at the opening of the MGM Grand at Foxwoods, presumably because he's dating Jennifer Aniston.) At the same party, Nick Cannon had to cut short a boys' night out with Sean Combs and Quincy Jones after wifey Mariah Carey called him at 1 a.m. Marc Jacobs will be featured in drag on the next cover of Interview magazine. (He's also back with ex Jason Preston.) Graydon Carter kind of comes off as an asshole in the movie version of Toby Young's How to Lose Friends and Alienate People. Keith Olbermann and Bill O'Reilly totally hate each other. Like, really.

Derek Jeter and a friend ate pasta and had a boys' night out at Nino's Positano. Owen Wilson hung out at a Philadelphia strip club and drank beer for four and a half hours after breaking up with Kate Hudson. Jesse Metcalfe trashed his hotel room in San Diego. Scarlett Johansson skipped Cannes because she didn't get her own makeup artist. Rumer Willis drank Red Bull and danced at the Plumm. Gene Simmons has written a book about the 4,800 women he claims he's slept with. Lynn Spears and Real Housewife Jill Zarin hung out backstage at Z100's Zootopia concert in Jersey on Saturday. Diddy ordered a Kamikaze at Lupe Fiasco's show at S.O.B.'s. Dolly Parton is pissed off at Howard Stern because he made an audio mash-up tape of her saying dirty things.
