Robert Pattinson Admits To Envying Taylor Lautner's Body

Taylor Lautner has gained fame for his fab bod, as seen in the Twilight series, and it turns out Taylor's pecs have taken a toll on co-star Robert Pattinson!

Pattinson might be known as heartthrob Edward in the series, but he got nervous for the upcoming film, Breaking Dawn: Part I, when he found out he'd have to do shirtless scenes!

Pattinson tells Mexican magazine 15a20:

"You ... have to worry about how you're going to look. I had never been so worried about that before, but after seeing how much Taylor [Lautner] works out for the movies, I thought, 'Well, everybody is really going to judge me now. I always tried to think about positions where I could tense the muscles, and suck in my belly. I think I just gave the most vain answer I could come up with."

Rob says he worked out for Breaking Dawn, but he couldn't quite achieve that Lautner physique!

"I thought, 'Okay, it's the last one [movie], I'm getting a six pack,' and I tried, but it's very hard. I worked out so hard for six months, so after filming the sex scene, the first thing I thought was, 'Time to eat!'"
