A source described the encounter between Rob Pattinson's ex girlfriend and rumored current girlfriend: "It was weird when they saw each other, because Kristen didn't look very happy when she walked over to give her a hug.  They spoke for like two minutes and then Riley and her girlfriend walked away. Kristen watched the show from upstairs and I am pretty sure Riley kept her distance and was watching from downstairs."

According to recent reports, Pattinson and Keough have been 'hanging out and hooking up'.

"She is the first girl he has liked since Kristen. They're having a lot of fun," the source said.

Riley Keough has been making a name for herself in the modeling world, modeling for a brand of Lingerie.
