Julianne Hough 'Rocks' Fresh Breath

Nothing is bound to throw off your rock and roll groove like someone who tries to get way too up close and personal with you after eating a potent dinner. Yuck. Haven't they heard of a personal bubble? Luckily, MTV News' Josh Horowitz won't have to worry about that tonight during Sneak Peek Week, because Julianne Hough is already popping Altoids to keep her breath smelling fresh.

The "Rock of Ages" actress and her co-stars will round out our week-long coverage leading up to the 2012 MTV Movie Awards. First, our very own host Russell Brand will be on-air at 11 p.m. ET to introduce an exclusive clip from the highly anticipated movie musical. Immediately following, you can log on to MTV.com to catch Julianne, Diego Boneta, Malin Akerman and director Adam Shankman during a special live Q&A session.
