The buzz is that Kristen Stewart is not interested in dating Robert Pattinson anymore. Apparently, she has developed a certain level of closeness with her "Camp-X Ray" co-star Lane Garrison. Reports have also suggested that this is the reason why K-Stew has denied Robert's request of spending Christmas in London.

"During the shoot of the film Kristen was enjoying Lane's company and he was spending a lot of time with her at her home," says a source to Yahoo's Omg! "He doesn't live in LA so he moved out of his hotel when they became close and moved into the guest wing of her house in Los Feliz."

Regarding the K-Stew-Lane Garrison romance, Hollywood Life has the scoop.

"Kristen Stewart is an amazing athlete and an amazing golfer. We built a driving range on the set of Camp X-Ray and she can hit the ball perfectly straight like 220 yards, adding, She's awesome.Great golfer, she can throw a football pretty well, and she's really good at basketball. We had a blast - she was having a great time!" claimed Garrison.

In "Camp-X Ray," Kristen Stewart plays a soldier named Cole who develops a questionable relationship with a prisoner. Peter Sattler is directing the film.

"She's great in this movie - no diva antics whatsoever," added Lane. "This film's going to be very powerful. It's about Guantanamo Bay and what we should do with the detainees down there so I think it's going to be very powerful."

We wonder what Robert Pattinson has to say about the growing closeness of Lane and Kristen. Is K-stew again cheating on R-Ptaz with Lane or is she just friends with him?
