There have been constant rumors surrounding former Twilight couple Kristen Stewart and Robert Pattinson, and now reports are saying that the two are not only still in contact, but they possibly had a one-night stand.

Robert Pattinson Dishes On His 'Optimistic View Of The World'

On Wednesday, Hollywood Life posted a story from In Touch Weekly that mentioned that Pattinson was partying with pop star Katy Perry in Westwood. After the alleged wild night, the report says that he went over to Stewart's house where they "definitely hooked up."

"He stayed at her house while he was in town," a source told the magazine. "She still loves Rob and would love to be with him again. But he's having fun and doesn't want to be in a committed relationship right now."

Robert Pattinson Has Something To Smile About?

The actor has reportedly been staying with Stewart during his time in Los Angeles because he apparently doesn't have anywhere else to stay.

"Rob doesn't have his own place in L.A. When he's in town, he sometimes stays at the Chateau Marmont and very often at Kristen's when she's out of town," a source told the site. "This gives him the chance to hang out with [their dogs] Bear and Bernie."

Pattinson recently spoke with The Telegraph on what his life came to ever since Twilight became a big deal. He revealed there were some difficulties, and that he couldn't do a lot of stuff he used to do.

"But once I got through that a year or two ago I just accepted my life is something else and now I can't really remember what it was like before so it's much easier to deal with," the actor said.
