Miley Cyrus strips down to red bra and tiny shorts for her new film So Undercover

Not so long ago, she was one of Disney's most beloved teenage stars, appearing on hit tween show Hannah Montana and playing sold-out concerts to thousands of young fans.
But Miley Cyrus is clearly growing up fast, judging by these photographs from her latest movie.
The 18-year-old star strips down to a pair of short orange and red night shorts and a lacy red bra in one scene from So Undercover.
