Miley Cyrus Premieres Movie, Boyfriend Liam & Leather Dress (PHOTOS)

Miley Cyrus and boyfriend Liam Hemsworth made their red carpet debut as a couple at the premiere of "The Last Song," which they star in. They met when the Australian auditioned to play her love interest in the film.

Miley, 17, is looking increasingly grown up and donned an asymmetrical leather (fake or real, unknown) black dress with her hair swept up. Earlier this week her hair delayed her private plane flight for four hours.
