Kelly Clarkson showcased her dazzling smile and looked gorgeous in a chic mini-dress as she walked the red carpet and performed at the 2015 iHeartRadio Summer Pool Party on Saturday.

The event took place at Caesar's Palace in Las Vegas. The 33-year-old singer sported a short-sleeve cream and yellow lace frock with a white tulle overlay, paired with a skinny tan belt and matching ballet flats with black bows. No uncomfortable stilettos for this lady!

On stage, she belted out her first big fast-paced pop smash hit, "Miss Independent," released in 2003, less than a year after she won the first season of American Idol.

 She also performed her 2004 song "Since You've Been Gone" and her latest single, another pop anthem, titled "Invincible," whose inspiring music video was recently released.

The iHeartRadio Summer Pool Party also featured other American Idol stars. Former judge Nicki Minaj, 32, took the stage in a cleavage-baring hot pink, green and white Moschino spandex outfit, while Adam Lambert, 33, who came in second place during American Idol's season 8 in 2009, performed as well.

Katharine McPhee, 31, a season 5 runner-up, Smash alum and current star of the show Scorpion, was also spotted at the event, wearing a leopard mini-skirt, beige top and cream cropped jacket.

Other performers included Nick Jonas and David Guetta.
