Pop superstar Miley Cyrus is laughing off claims she has signed up to play a promiscuous teen in a racy new R-rated movie. The 15-year-old sensation has been linked to new film "Undiscovered Gyrl," which is based on a novel by Allison Burnett.

Sources close to Cyrus, who caused controversy by posing topless and wrapped in a bed sheet for August's Vanity Fair magazine, claim the Hannah Montana star is interested in the project.

The part Cyrus is reportedly considering is that of a "lost suburban girl who descends into a life of reckless partying and promiscuity," and insiders insist the project could even contain nude scenes.

Cyrus' spokesperson has refused to comment, but the singer/actress is adamant the report is bogus. She says, "I'm not even allowed to go see R-rated movies."
