Aww another pic without TomStu. I guess these girls are missing out of not asking him.
This fan says that Kristen joined the boys later in the evening after filming. Well, nothing surprising about that. She said that she was wearing a hoodie and looked very tired. Luckily, noone bothered them anymore after that (her arrival? I assume). The resto owner deterred pic seekers, as well.
ETA: New Pic via source
I assume this was before Kristen arrived... Rob is really very, very kind to fans. lol
