Kellan Lutz accidently hurt Robert Pattinson on the New Moon set.

They might get on really well in real life but Kellan couldn't help hurting Rob whilst filming one of their scenes together.

Rob and Kellan were filming a scene which involved their bodies colliding.Kellan explained to OK: ""He didn't think I'd actually nail him, but that's what the script said I was supposed to do.

"I didn't go out of my way to hurt him, but there is Rob, trotting along, and bang!"
