In the "Breaking Dawn" trailer we see Edward Cullen take his new bride Bella on their honeymoon retreat, and it’s there that we get a short glimpse of his bulging back when he BREAKS THE HEADBOARD in a fit of passion.
After seeing the scene, however, some wondered if Rob actually used a body double. Well, we caught up with his "Twilight" co-star Kellan Lutz, who blessedly assured us that it was all Rob."Someone asked if that was me. Is that Kellan’s back?" the 26-year-old actor said, laughing at the idea. "I’m really proud of Rob for working out and really training really hard. He cycled so hard and trained very hard, and he’s really diligent. He talked to me about what proteins to drink and what to do and he listened and cared. He had a great mentality for it."
