HOLLYWOOD, Calif. — Miley Cyrus' new music video for the song "When I Look at You" has leaked onto the Web.

The track is from the 17-year-old star's upcoming movie The Last Song, which hits theaters on March 31. The film, based on Nicholas Sparks' best-selling novel of the same title, revolves around a rebellious teenager (Cyrus) who has to spend the summer with her estranged father, a concert pianist.

Cyrus' co-star and real-life boyfriend, Liam Hemsworth, is also featured in the "When I Look at You" video.

The single is produced by Adam Shankman and Hillary Lindsey.

"'When I Look at You' was actually a song that was going to go on my next record," Cyrus explains in a behind-the-scene clip of the video shoot. "We listened to it and went, 'Oh my gosh, this could not be more perfect.' It describes the entire movie."
