No Doubt had the crowd on their feet and dancing when they opened the iHeartRadio Music Festival in Las Vegas with "Hella Good" on Friday night.

A fan tried to grab Gwen Stefani's rock hard abs as she made her way to the stage.

The band kicked it old school with "Spiderwebs" and Gwen told the fans they looked "beautiful and delicous" before jumping right into "It's My Life."

The band debuted their "Lookin Hot" single from their upcoming album "Push and Shove" Tuesday, September 25th.

The electrifying preformance continued with "Don't Speak" and we got our first surprise of the weekend when P!nk joined No Doubt on stage for "Just A Girl!"

And yes, that's P!nk doing push-ups! The set wrapped up with Gwen and P!nk hugging!

Blonde girl power!
