The `Twilight Saga: New Moon` actor - who underwent months of physical training to bulk up for his role as werewolf Jacob Black in the franchise - gets overwhelmed by the attention his physique receives from fans.
He said: "It has become embarrassing. It doesn`t annoy me but people do tend to ask about it a lot. To me it`s just part of the character. It`s not like I can take it off!"
It has previously been claimed that the 17-year-old star would like to become a personal trainer if his acting roles dry up.
A source said: "His self-esteem shot through the roof when he bulked up for `The Twilight Saga: New Moon` and he wants other people to experience that feeling."
One person who would love to train with the actor is Justin Bieber, who is said to be working with a fitness expert to get a physique like the star.
A source said: "Justin`s positive he has the intensity and focus to get the same results as Taylor."
Taylor - who put on over 30lbs for his part in the film franchise - has previously said his motivation for the muscle gain was the "movie and the fans".
