Robert Pattinson excited about pillow-biting sex scene with Twilight co-star

Robert Pattinson has revealed that he is looking forward to a “pillow-biting” sex scene with his co-star Kristen Stewart in new Twilight movie Breaking Dawn.

In the fourth and final film adaptation of the vampire saga, the pair share heated sex scenes and Pattinson, 24, revealed his excitement about the intimate scenes.

Pattinson, dubbed R-Pattz by fans, told Access Hollywood: "I'm looking forward to the pillow-biting scene.

"I thought that was so funny, of all the random things too do, really? He bites the pillow."

Stewart, whose character Bella Swan has a baby in the new movie, added: "It does actually literally get more physical [in Breaking Dawn].

"It doesn't get more action-packed… [But] they definitely get more physical – well, they get married…

"We totally have sex – finally!"
