Kristen Stewart and Robert Pattinson: Jealous Fights About Sarah Roemer?

There’s trouble in Robsten land. According to a new report from Us Weekly, “tempers are short” for Kristen Stewart and Robert Pattinson and the couple are arguing endlessly, each accusing the other of infidelity.

Rob’s flirtations have been well-documented. He was spotted having dinner in LA with actress Sarah Roemer while Kristen was in England filming Snow White and the Huntsman. She’s said to be particularly upset over reports that Rob was seen “stroking” Sarah’s hand. Apparently, Kristen has long been uncomfortable with Rob’s heartthrob status, and the reports about his night with Sarah represented “her worst fear realized,” according to a friend.

But Kristen’s not the only one who’s feeling a little insecure these days. Rob is reportedly pissed that Kristen has been spending a lot of time with her On the Road co-star Garrett Hedlund. “Rob’s in total panic mode at the thought of losing Kristen,” says the anonymous insider. He’s so worried, in fact, that he supposedly bought her a crazy expensive diamond ring for Christmas. Might there be a wedding in the near future for the real-life Edward and Bella? If so, hopefully the honeymoon is a little less violent.
