PEEK-A-BOO

Hilary Duff shows off a little skin in her cutout black dress as she presents during Saturday's show. "I'm here to have fun," Duff told radio host Elvis Duran before introducing "All About That Bass" singer Meghan Trainor. "I was going to wear a butt pad tonight, but then I didn't!" she joked.
