No Doubt brought their ska-pop act to Las Vegas’ MGM Grand Garden Arena for the iHeartRadio Music Festival. They revisited some of their old material, including Tragic Kingdon’s “Just A Girl.” Mid-performance, Gwen Stefani invited screaming diva Pink to hit the stage for a grand duet.

The “Blow Me” pop rocker walked on stage, bowed to her pop superior, did a few push-ups and began belting out the tune. The seasoned acts put on a “rad” show.
