No Doubt and Pink perform at the 2012 iHeartRadio Music Festival.

The 2012 iHeartRadio Music Festival was the definition of action-packed last evening. In addition to performances by Rihanna, Keyshia Cole and Lil Wayne (all of which you can watch here), No Doubt were live onstage with none other than Pink!

Surprising their fans with the unexpected collaboration, No Doubt and Pink rocked the iHeartRadio Festival with a rendition of ‘Just a Girl’. Moreover, after a few rounds of pushups and rocker vocals, the former act then debuted their new ‘Push & Shove’ single, ‘Looking Hot’, live.
