A quick rumor that Miley Cyrus was going to star in "Undiscovered Gyrl" has been kaboshed even more rapidly by the tween superstar. Miley has been under heat lately for wearing a 'chastity ring' yet posing for somewhat provocative pictures. That's a far cry from the image of her that would be presented by her appearance in 'Undiscovered Gyrl.'

Miley already dismissed the report by saying, "I'm not even allowed to go see R-rated movies."

Considering that her audience is made up mostly by tween girls who look up to her as the Second Coming, it would be shocking if she were to star in a movie that's supposed to be about a "lost suburban girl who descends into a life of reckless partying and promiscuity."

As far as we know, Miley hasn't even been kissed yet, so it's highly unlikely she'd be the one for a role like this. Now, Lindsay Lohan, if she was a bit younger would be perfect for such a role.
