Miley Cyrus: 'No Sex Before Marriage'

"Hannah Montana" star Miley Cyrus is blasting back at recent reports that she's pregnant.

"Extra" caught up with the Disney sensation at the Us Weekly Hot Hollywood party, where she finally addressed the nasty rumors.

"It's given me the street cred to say that would be impossible, because I'm living my life the way I believe is right and that is to stay pure," she insisted.

Miley, 14, added that she does not believe in sex before marriage. "No, I don't at all," she said.
