Hollywood has a way of changing people in both good and bad ways. If fans loved Selena Gomez's transition from Disney darling to sultry singer, not many appreciate Miley Cyrus' drastic change from Disney sweetheart to nude singer. Here are other shocking celebrity transformations.

The Miley Cyrus now is definitely a far cry from the "Hannah Montanna" version. Cyrus no longer rocks the long brunette hair but has the bleached blonde boy cut instead. The hair isn't the only visible change in Miley's look but her choice of clothing or lack of it. In her recent video release, "Wrecking Ball", Cyrus goes completely nude for the song. "Smilers" may love Miley's change but not all Disney fans are pleased with it. As for Miley, the "We Can't Stop" couldn't care less what her haters had to say.

"It's called puberty. Everyone's done it from the beginning of time. I'm just doing it [in the spotlight] so you're zooming in on it and you're fascinated by it," said Miley in an interview with Fashion Police, adding, "I think if I can just use where I am in my career and use myself as a pedestal to do good - even if it means getting naked, 'cause more people are gonna look at it."

The "Bangerz" singers' change may be a bit acceptable compared to Amanda Bynes' extreme change. The former Nickelodeon star has gone from Hollywood hottie to a complete mess. As of late, Bynes is currently being treated at a mental facility.
