Miley Cyrus' Advice to Teens: 'Decide Who You Want to Be'

Miley Cyrus is officially the queen of the teens.

Her Best of Both Worlds tour has been the hottest ticket of 2007, with parents paying thousands of dollars for their kids to see Hannah Montana rock the stage.

So how does the 15-year-old star keep her head on straight? With a lot of help from her dad, Billy Ray.

"The only people that you really have, that I learned, are your family, because they love you no matter what," Miley told "Extra."

And a little-known fact about the singing sensation? Her real name is Destiny Hope. She was nicknamed Miley because she smiled so much as a kid.

Now she has advice to the millions of fans who look up to her.

"With yourself, I think you have to decide the kind of person that you really want to be, and for me, it's just a sweet girl," she said.
