'Hannah Montana' star defends leaked photos

Hannah Montana star Miley Cyrus has defended leaked photos showing her playing around with a friend.

They show the 15-year-old and another young female rolling around on the floor of a hotel. In one they are eating opposite ends of the same sweet.

Some have apparently said they are inappropriate for a children's television actress, but Cyrus insists they are innocent fun.

"They're nothing bad! It's not something I'm going to let slide," she declared. "I'm really upset about it, 'cause it was, like, not even a big deal.

"That's one of my best friends. I have all these girls who I hang out with all the time. It's two girls at a sleepover, and if all of a sudden that's bad, then what is the world coming to?"
