Kristen Stewart really knows how to travel in style! The surly movie star boarded a private jet at an airport in Van Nuys, Calif., on Monday afternoon -- and it's very possible that the Twilight star is headed off to London for a rendezvous with on-again/off-again love Robert Pattinson.

RPatz flew back to the UK this week to get ready for the holidays and is said to have invited the 23-year-old to spend Christmas with the 27-year-old. The website Entertainmentwise is reporting that the hunky Brit called his ex to congratulate her because her new movie, Camp X-Ray, was accepted into the 2014 Sundance Film Festival and then extended an invitation to visit him in London for the holidays.

While we haven't spotted the duo together in some time, there are reports that the former flames have still been seeing each other and were even planning on spending Thanksgiving together.

"She is making a few dishes that Rob grew up with like Yorkshire pudding, cauliflower cheese and roasted parsnip. Kristen really wants to impress Rob and make him feel at home. She's really putting her all into this dinner," a source told Hollywood Life.

While we love love -- we definitely hope for RPatz sake -- that he really has kicked Kristen to the curb. He's way too good for her!
