Transformation

With little besides a blond wig separating her from alter ego Hannah Montana, it's a good thing 17-year-old Miley Cyrus has a strong sense of self. "I like being myself, doing my thing," she has said.

"I've had my awkward stage," she has said, "but luckily everyone sees me with my makeup on."
