New York, February 26 : 'Twilight' star Robert Pattinson appeared with a beer constantly in hand, and showed no signs of slowing down, at Patrick Whitesell's recent bash.

"I'm planning on staying up all night. I've got a flight to Toyko in the morning, and there's no point going to bed. I'm just going to pull an all-nighter!" the New York Daily News quoted him as telling a throng of admirers.

He also found some time to chat with a mascared and guy-linered Jared Leto.

Guests attending the party also included Benicio Del Toro, Zach Braff, Mary-Kate Olsen, and Jeremy Piven.

The newspaper also said that Uma Thurman's ex-boyfriend, hotelier Andre Balazs, was caught cuddling with Sharon Stone at Guy Oseary's L. A. home on Sunday night.

"They were on the couch by themselves literally all night. They couldn't have been more into each other," says a fellow guest. (ANI)
