You gotta love Ed Westwick.

Like his Gossip Girl alter ego Chuck Bass, he has become accustomed to late nights in NYC, the New York Post reports.

The British actor hit the Beatrice Inn Monday night, where he threw back whiskey shots and "flirted with every girl there."

"He was completely trashed and dancing with a group of girls that were all over him," said a Post spy.

Ed Westwick partied late night in New York City.

He was also overheard talking music with DJ Reach, saying his band, the Filthy Youth (his co-star Leighton Meester checked out his most recent concert), was better than most American ones.

"He was yelling that all other bands were rubbish," said the source.

Ed Westwick stayed until closing time.
