Miley Cyrus worried she could end up washed up

Hannah Montana actress Miley Cyrus is worried she could end up washed up.

"Miley loves being successful -- she doesn't know anything else. But she's worried she could end up washed up like all the other former teen stars out there.

"Turning 18 has got Miley thinking about her future in Hollywood and how she's going to keep her career white-hot for as long as she wants it to be."

Miley recently insisted she puts her career above all anything else.

"I definitely don't want people to think I'm trying to get married anytime soon," she said. "I'm way too driven right now, first of all, I'm 17, it's ridiculous, and second of all, I've got so much work I want to get done. I have so much to do, there's no way it's happening.
