Sandra Bullock mr chow hotel jacket hollywood

Sandra Bullock had a wild Wednesday night!

The actress enjoyed dinner at Mr. Chow before heading over to the white hot Beacher's Madhouse at The Roosevelt in Hollywood, where she stayed until 2 a.m. Sandra knows how to party!

Bullock looked dazzling in dangly gold earrings. We're glad she had a night out to relax -- this week Sandra's rep had to deny rumors that she's "obsessed with being skinny," as one magazine cover claimed.

And she has better news to celebrate -- the trailer for her new flick Extremely Loud and Incredibly Close debuted Wednesday to rave reviews. The movie comes out in December and is already getting Oscar buzz! Watch after the jump.
