Robert Pattinson may spend Christmas with Kristen Stewart.

The Twilight Saga actor is reportedly being forced into a decision over staying in Los Angeles with his former flame or returning to his hometown of London to be with his family - who allegedly disapprove of rumors the couple have rekindled their on-off romance.

"He's supposed to go home to London for Christmas, but Kristen wants him to stay with her in LA. He's torn," a source revealed to Life& Style magazine.

Robert's family are distrusting of Kristen following her alleged affair with married Snow White and The Huntsman director Rupert Sanders last year, and fear the Christmas holidays could spark a reunion between the pair. "They can't stand Kristen; his family is terrified that he'll never get away from her. They think she's bad news, but there's something about Kristen that he just can't resist," the source added.

While Rob remains undecided over his Christmas plans, sources have revealed to Hollywoodlife.com that the pair will spend Thanksgiving Day making traditional English dishes together.
