Kristen Stewart reportedly lives with her new boyfriend Lane Garrison, three months after her May spilt from Robert Pattinson.

Stewart's Camp X-Ray co-star moved into the acttress' Los Feliz home she once shared with Pattinson, according to sources. The couple bonded during filming for her upcoming movie. Stewart plays a U. S. soldier stationed at Guantanamo Bay and Garrison plays a superior officer who forces himself on her.

"Kristen was enjoying Lane's company and he was spending a lot of time with her at her home," a source told Yahoo! 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."

According to the source, Stewart's family is concerned about her budding relationship with the actor because of his secret past -- he spent three years in jail for vehicular manslaughter. His 2007 drunk driving incident killed a 17-year-old and led to his jail stint.

The source also said Stewart's brother is especially worried about her new friendship.

"Kristen's big brother, Cameron, has told her he's concerned about the new relationship, especially since his recent arrest after his jail term," the source revealed. "Garrison still attends Alcoholics Anonymous meetings."

"He's a much darker person than Rob and still goes to mandatory AA meetings every week following his battery arrest," the source added. "She understands his violent past but trusts that he's changed and is really enjoying getting to know him."

Garrison is most known for his role as David "Tweener" Apolskis on Prison Break from 2005-2006. Earlier this year he appeared in the Bonnie & Clyde television series.
