Ashley Greene was dancing the night away with her Twilight costar Xavier Samuel at Lavo's grand opening in New York. The costars were literally by each other's sides all night, just laughing and hanging out. Upstairs, True Blood's Joe Manganiello dined with model-actress girlfriend Audra Marie, and the actor feasted on a special no-carb meal cooked especially for him because of his strict diet. According to an onlooker, the two "were really cute, kissing and cuddling the whole time."
