Well hello, muscles — Kellan Lutz showed off his seriously ripped biceps on his way to a class in LA this week. As his costars continue filming New Moon, now including Dakota Fanning, Kellan seems to be doing a fine job of keeping himself sexy here in the states. Earlier this week he mingled with some of Hollywood's pretty young things, but these days Kellan and his hot Twilight guys seem to be turning more heads than the starlets in LA.
