Julianne Hough and Diego Boneta star alongside Tom Cruise in this month's Rock of Ages, and when we caught up with the duo at a recent press day for the movie, they dished on Tom's surprising singing and dancing skills. Rock of Ages' release will kick off a busy Summer for Julianne. She told us that, sadly, she won't accompany boyfriend Ryan Seacrest to the Olympics in London because she's set to start filming Nicholas Sparks's Safe Haven around the same time. Meanwhile, Diego is gearing up to make his big-screen debut in front of US audiences with his role in the musical movie. He also chatted about his international music career and his plans to work with Adam Levine. Rock of Ages hits theaters June 15.
