RPattz and Kristen Stewart Cozy Up at Concert

Rob Pattinson's good friend Sam Bradley performed at Vancouver nightspot Richard's on Richards on Saturday night, and boy, did things get heated!

Wearing a hoodie that covered his signature, tousled locks, RPattz cheered on his pals in a backstage corner, standing next to his co-star and rumored love-interest Kristen Stewart. Looking like he was having the time of his life, Rob kept whispering to Kristen and, at times, looked like he was about to kiss her.

While Rob has repeatedly laughed off rumors of a possible romance with Kristen, the couple seems to be more than just friends when they're caught off guard by the ever-lurking super-fans and paparazzi.
