It looks like the news of Kristen Stewart and Robert Pattinson getting back together could be even more likely since the two might be hooking up- although it's not exclusive.

Kristen Stewart In "Feisty" Mood Lately?

On Wednesday, Hollywood Life reported that Pattinson was in Los Angeles on April 1 after wrapping up his upcoming film Life. Allegedly, the actor was headed towards a fancy chateau with a female driver, which created speculation on who that woman could've been.

Though according to a source, it might not matter since things might not be over between him and his former Twilight ex-girlfriend. Not only could the two still be close, but they might even be sleeping with each other as well as with other people.

"Rob and Kristen talk all the time and they're still hooking-up, but it's not at all exclusive," an insider said. "I guess you could call it an 'open relationship.' As much as they both love each other, there are no rules in place. It sounds like a crazy way to live, but it's so common in Hollywood."

Kristen Stewart & Robert Pattinson Never Getting Back Together?

The source also mentioned that Rob doesn't plan to get it on with too many girls because that's supposedly not his thing.

"That's not his style, he's not a huge womanizer the way a lot of guys in Hollywood are," the source said. "Rob would rather get drunk with his friends than pick up girls, and that's what [April 1] was all about. He wasn't there to meet anyone, it was just a fun night with the people he's working with. Who doesn't like to go for drinks after work, right? Rob's no different- once the stress is over he likes to unwind."
