It's time to roll down the windows, turn up your favorite jam and set sail into days filled with sunshine, smoothies and flip flops. Summer is here, and no one knows how to kick it off better than iHeartRadio.  

The iHeartRadio Summer Pool Party, held for the first time ever at Caesars Palace in Las Vegas, was off the charts. But no worries if you didn’t make it out—we have the complete behind-the-scenes scoop:

Kelly Clarkson crushed her opening performance (as always), but before she did she caught up with iHeartRadio’s Romeo backstage where she learned that she's also crushing it on iHeartRadio!

Nick Jonas showered fans with water from the stage, but not before he made sure he got a photo with Bebe RexhaJealous?

Bebe was definitely having a good time and rocked it out on the red carpet, before she rocked it out on stage for a surprise performance that the crowd couldn't get enough of.

Echosmith may sing about not being #CoolKids, but they looked pretty awesome backstage having a little fun with some inflatables.

Shaggy (a.k.a. Mr. Lover Lover) hit the audience with his new jam "I Need Your Love," but not before bringing down the house with his classic "It Wasn't Me." It was him on the red carpet, though, and boy is he charming.
