Taylor Swift, Linkin Park, Pink, Ne-Yo keep it classy during Saturday's iHeart Radio Musical Festival

After Green Day's Billie Joe Armstrong created something of a commotion by walking off the stage Friday night in a profane laced tirade, things got back to business Saturday. Pink, Enrique Inglesias, Brad Paisley and Mary J. Blige sang some of their latest hits to a packed Las Vegas audience. One highlight was Ne-Yo and Calvin Harris performing together.
