"They weren't obviously all over each other, but it seemed like they were together," dishes a fellow celebrating source. "There were times when they would be sitting down and he would kind of lay his hand on her knee. They were smiling, laughing, they looked happy!"

This whole thing sounds awfully cozy for two good-lookin' babes who are just friends, no? Blake and Ryan were first spotted undercover in October at Disneyland, and while Lively's rep denied they were there on a date, it was announced Blake split with longtime BF Penn Badgley two weeks later. One guy very much in the NYC scene (who has a hilarious recap of last night, you must read) believes B and R to be dating. But dating is so often such a meaningless term these days, is it not? Our spy adds that Blake and Ryan didn't leave together. We've put in calls to Lively and Gosling's reps but have yet to hear back.
