It's officially summer, which can only mean two things: celebs and pool parties!

We got a dose of both on Saturday at the iHeart Radio Pool Party, which was held for the first time ever at Caesar's Palace in Las Vegas. Everything about the night was blazin' hot -- from Chris Brown's bright yellow pants to Nick Jonas' swoon-worthy vocals.

The show's headliners included Nicki Minaj, Echosmith and more.

Kelly Clarkson opened the party with an electrifying performance, while Nick Jonas apparently felt the heat as he showered fans with water on stage during his rendition of popular hits "Jealous" and "Chains."

Chris Brown came on stage and demanded that the bikini-clad crowd, "turn up" – he didn't have to say it twice. He certainly turned up the temperature more than just a few notches with his super smooth dance moves.

Of course, no pool party is complete without a couple of throwback jams. Shaggy got everyone movin' and groovin' with an oldie but goodie performance of "Wasn't Me."

But the award for the best performance goes to Nicki Minaj, who absolutely stole the show dressed in a neon bodysuit and Air Jordan sneakers. The sexy superstar performed a collection of her most popular songs before closing the show by bringing out David Guetta and Bebe Rexha for their new single "Hey Mama."

Here are a few of our favorite moments from the music extravaganza:
