Miley Cyrus by Rick Diamond/ Miley Cyrus by Rick Diamond/
Miley Cyrus has been the poster child for the rare combo of superstardom and restraint, but things may be changing. The teen phenom is coming out with her personal memoir via the Disney Book Group - but that's not all. Just as she made the announcement, she may have revealed a little more of herself, with some bra-baring poses in pics purportedly of her. In a statement to the AP, Cyrus promises that the book - due out next spring - will be about her mom's role in her life and the importance of strong family bonds. "I am so excited to let fans in on how important my relationship with my family is to me," she says. "I hope to motivate mothers and daughters to build lifetimes of memories together and inspire kids around the world to live their dreams." In the meantime, however, Cyrus has possibly shared more than family values with her fans. In addition to the upcoming book, revealing photos of a young woman resembling Cyrus have been circulating on the 'Net. In one, she's pulling down a tank top to reveal a green bra, while in another, she's lounging, bare-stomached, on a guy with his hand on her hip.

TMZ, of course, has done us the favor of sharing. We've already seen some possible glimpses of the teen phenom experimenting with some seductive poses. Is Miley morphing from her squeaky-clean Hannah Montana image into a new arena? It's not the first time we've seen purported pics of her posing like a temptress, so is it part of growing up, albeit publicly? And can she reconcile her clean, tween self with the emerging adult inside? Dish it up. - Anna Dimond Use our Online Video Guide to see even more of Miley Cyrus.
