Singer Kelly Clarkson wore a cute mini-dress to the iHeartRadio Pool Party in Las Vegas over the weekend, according to E! Online.

Clarkson gave fans quite a treat at the event when the 2003 "American Idol" winner sang her 2003 post-show-winning hit, "Miss Independent," that helped her rise to fame even more. She followed this epic performance with her 2004 banger "Since You've Been Gone," and then her current record, the 2015 release "Invincible."

Chris Brown, Nick Jonas, Nicki Minaj and David Guetta joined Clarkson as the main headliners at iHeartRadio's annual attraction at the Vegas Strip's Caesar's Palace, according to the Las Vegas Review-Journal.

Singers Adam Lambert and "American Idol" fifth season winner Katharine McPhee also joined Clarkson in the spotlight, justjared.com reported.

"Thanks everyone! See ya at the concert #iHeartPoolParty #iheartadam," Lambert posted on his Twitter account a few hours before the wet and wild extravaganza got under way.
