lol, from datalounge.
"I was at the after party last night and if this is a PR stunt, they're acting this out better than they act in any of their films. I observed them being very sweet with each other, so if they're not dating, they're very, very close. I hate to admit this but they are really adorable together. They stayed very,very close to each other for most of the night. They sat with Rob's parents and sisters talking and laughing with their arms around each other for a long time. I didn't see Kristen's parents, or if I did, I didn't realize it was them, by the way.
They held hands at one point and were just generally very couple-y, if you know what I mean. They whispered to each other quite a bit and Rob touched the small of Kristen's back several times. I didn't see them kiss but they kind of nuzzled each other at one point. Like I said before, if they're not together then they're great at faking it."
