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.

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

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.

The source added: ''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.''

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.
