Earlier this month we reported the news that shook the Twilight world, Robert Pattinson possibly cheating on Kristen Stewart!

This all went down in L.A. where Rob was spotted having an intimate dinner at La Poubelle with actress Sarah Roemer, while Kristin was filming Snow White and the Huntsman in England.

Once she found out the news from across the pond, the Twilight star was reportedly fuming!

A source reveals, “Rob’s one of the world’s biggest heartthrobs and Kristen’s never been able to relax the whole time she’s been with him. This was, like, her worst fear realized.”

Pattinson has shot down the cheating rumors saying it was only an innocent dinner with a friend, but Kristin isn’t having it.

Now the 25-year-old vampire actor is terrified his long-time girlfriend is going to leave him.

Sources say he is desperately trying to save their relationship.

Here’s my question: Why? He can get anyone one in the world, but I guess to each their own.

Anyways, good luck you two.
