Are her breasts naturally that size? I ask because I know that she was Playboy's "Cyber-Girl of the Week" back in 2007 (which I really wish they hadn't done because she deserves better than that), and I also know that the scumbags who run that horrible magazine often pretty much require their models to mutilate their breasts via implants in order to get accepted.
(By the way, I'm not against the magazine for religious reasons - in fact I consider myself atheist - but rather for humanitarian ones, as I consider it exploitive of the young women who participate. I also have nothing against artistic depictions of nudity - quite the opposite, in fact. It's just that I feel that women's bodies are beautiful - and Carly's is certainly no exception - and should be treated with respect and reverence like in this image, not scorn and ridicule like in Playboy.)
