Kristen Stewart is ready to take a bite out of Robert Pattinson.

Tabloid insiders claim the 18-year-old actress is jealous that the British hunk ,who plays her on-screen vampire love interest in the Twilight film franchise, has turned into a media darling overnight. Star spies claim Kristen has been belly-aching to anyone who will listen about the all of the attention Robert receives almost effortlessly, while she on the other hand can barely squeak through her interviews on late night TV.

After all, she is the movie’s main character.

“She’s sick and tired of hearing about him all the time,” a insider gushes. “Except for filming together and mandatory work functions, Kristen refuses to be in the same room as Bob.”

In other Twilight news, this winter’s box office hit arrives on DVD at midnight on Friday, March 20.
