Miley Cyrus Goes 'Undercover' in New Orleans

The 18-year-old actress stars opposite Kelly Osbourne, Megan Park, Joshua Bowman and Matthew Settle in the flick.

So Undercover follows a tough, street-smart private eye (Cyrus) who is hired by the FBI to go undercover in a college sorority. Miley recently opened up about the street fighting training in the flick, too.
