Miley Cyrus' sexy new video

Once upon a time she was little Hannah Montana.

But the teenager's growing up fast as these pictures from a new video show.

The 17 year old stars alongside Gossip Girl star Kevin Zegers in a ghostly love affair in the video for Rock Mafia's 'The Big Big Bang'.

In the video, which was shot in Los Angeles, Cyrus kisses Zeger several times - on a beach, in a car and at night on the street, as the lovers flit back and forth between reality and memories - before she is involved in a car accident.

Miley's latest album is entitled Can't Be Tamed.

Last month it was revealed the star's father Billy Ray Cyrus filed for divorce from her mother Tish.
