Hard partying celebrities are being spotted all over New York City by Bouncer Chronicles spies getting into the holiday spirit. Night club regular Rihanna was hanging with newly single Leonardo DiCaprio at The Meatpacking District's Up & Down. Also hanging out with that group was Jonah Hill, Michael Cera, Tobey Maguire and Ashley Olsen.

Later that night our sources said the group ended up at 1OAK to meet up with Bradley Cooper, who is starring in "The Elephant Man" on Broadway. Tyrese Gibson, Ne-Yo and the New York Knicks JR Smith were also partying the night away at a nearby table.
