Fifteen-year-old Miley Cyrus — better known as Hannah Montana — is the undisputed queen of all squeaky-clean tween media. She's the star of her own Disney Channel show. She has bestselling albums, a sold-out concert tour, a 3-D concert movie and an upcoming movie. She also has an upcoming feature in Vanity Fair magazine. Pictures from that photo shoot have been swirling around the Internet in the past few days, including one of her topless, clutching a satin sheet to her chest. A lot of her young fans are disappointed.
