Looks like it’ll be a lonely Christmas for poor Kristen Stewart, because she's apparently been summarily uninvited to celebrate the holidays with boyfriend Robert Pattinson's family.

Which may or may not have had something to do with the rather awkward Thanksgiving dinner she spent with them last month.

Originally, the couple had planned to spend Christmas together, but since Rob's 'Twilight' press tour has precluded him from seeing his family much recently, he instead decided to travel back to London for a Pattinson reunion -- alone and without the added drama that Kristen might bring.

An insider said, “Rob’s mum wanted him to spend Christmas with them in London and, before their [November] trip to the UK, that had been his and Kristen’s plan. From London, they were going to fly to Mexico for New Year.”

But along came the worst Turkey Day ever. Kristen and Rob were in London for the ‘Twilight’ premiere, so they had a meal with Rob’s family on Thanksgiving, and it was the first time she'd seen them since all that cheating nonsense.

Apparently, things were a bit tense. According to the source, “It was nerve-wracking for Kristen. She felt very uncomfortable and Rob’s sisters couldn’t be completely welcoming.”

Kristen always seems uncomfortable, so that's not much of an indication, but you can imagine that Rob’s family might be a bit leery of her, even if he’s decided to forgive and forget. After all, she very publicly humiliated him. Or maybe she just chews with her mouth open.

Regardless, it’ll likely be spiked eggnog for one at KStew’s house on December 25, and maybe even a single serving of champagne for New Year’s.
