Julianne Hough shows off her toned tummy on the red carpet at the 2012 MTV Movie Awards held at the Gibson Amphitheatre on Sunday (June 3) in Universal City, Calif.

The 23-year-old entertainer sparkled in a Sally LaPointe dress and Jimmy Choo shoes and finished her look with a Kelly Wearstler clutch and earrings.

“I’m a huge Black Keys fan, and I’m excited to see Russell Brand,” she said on the red carpet. Julianne, Russell, and Diego Boneta (pictured inside) hit the big screen together in their comedy Rock of Ages on June 15!
