Last week, we were thrilled when we heard that Rob Pattinson invited his old (and potentially current?) flame, Kristen Stewart, to spend the holidays with him in London. And although Kristen should be totally psyched about the invitation, reportedly she’s a little hesitant about accepting.

According to Hollywood Life, Kristen’s only qualm with spending Christmas on the other side of the pond is the possibility that it could cause drama among Rob’s family, who may not be her biggest fans because of the couple’s previous relationship woes — most notably, when Kristen cheated with Snow White and The Huntsman director Rupert Sanders.

Kristen would love to see Rob in London but she doesn’t want to be the source of any tension between Rob and his sisters,” a source close to Kristen says. “She feels like she’s on good terms with Rob’s mom after all the cheating drama.”

As Kristen and Rob attempt to get back what they had pre-cheating scandal, we can imagine it’s a pretty delicate time for their relationship and totally understand why Kristen would be worried about ruining their work so early in the game.

“If things were different with the rest of his family, she would be there for Christmas, but she still has concerns,” Kristen’s friend adds. “The last thing she wants is to bring any drama whatsoever to Rob’s world.”

No official statement has been made about their reunion just yet, but we were hoping a Christmas together would seal the deal. We’ll just have to stay tuned!
