Robert Pattinson and Katy Perry: friends with benefits?

Sources say that Robert Pattinson and Katy Perry are friends with benefits and they hook up on a regular basis.

“They’ve always been friends with benefits, they’re both very low-key — that’s why they like each other” an insider said.

After Perry broke up with John Mayer, Pattinson was her friend in need. “Rob has made [Katy] promise to count on him for support, like she did for him when he split for Kristen Stewart, the question is, how much comforting will go — they always had this really flirtatious relationship.” the source said.

“Katy’s too torn up for now to think about jumping into bed with anyone, but even she has joked that Rob would make an excellent revenge hookup! They do have a wonderful friendship, and they trust each other. No matter how down she is, Rob can always make her laugh, and she loves that.”
