Kristen Stewart may have turned down Robert Pattinson's invitation to join him and his family in London for Christmas because she has a new man in her life, according to The Stir.

Stewart has been romantically linked to Lane Garrison, who stars with her in Camp X-RayGarrison raved about the golfing skills of his co-star in an interview with Hollywood Life.  

"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. She's awesome," he said. "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!" 

Other reasons, such as Stewart's wanting to avoid any friction with Pattinson's family, were also being given for celebrating the Christmas holiday with her former boyfriend.  

Pattinson recently called Stewart to congratulate her after Camp X-Ray got picked up as a contender at the Sundance Film Festival, Enstars previously reported. The film, which recreates the titular detention facility in Guantanamo Bay, will premiere at the festival in 2014. The 27-year-old actor invited Stewart to see him in London over Christmas toward the end of their phone conversation, according to an insider.

While their fate as a couple is still in question, their onscreen love only seems to be growing stronger with time. It was revealed that Twilight Saga: Breaking Dawn Part 2, the third installment of the mega-franchise, was the highest-selling DVD and Blu-Ray disk of 2013.
