The two joined a large private party at Fleming's Prime Steakhouse this week, but didn't leave each other's side all night.
An onlooker said:
"Kristen and Rob were very couple-like. There was a lot of hand-holding, sitting next to each other. Everyone was talking around the room, but Kristen and Rob were just talking to each other, not really into the conversations everyone else was having."
Awww. Edward + Bella = Love.
