According to a lot of news reports RPattz is ashamed of pictures being taking with his shirt off.
Rob spoke below about being compared to his famously toned twilight co-star, Taylor Lautner:
"I have never been so worried about that (how i looked) before, but after seeing how much Taylor works out for the movies, i thought, well, everybody is really going to judge me now."
Rob sweetheart, YOU ARE AN AMAZING TALENTED SINGER AND ACTOR AND THERE ARE SO MANY WOMAN SUCH AS MYSELF WHO WOULD DO ANYTHING JUST TO MEET YOU. Do not be ashamed of the body you have, because all us girls love you the way you are!!
