Pop star Demi Lovato is impressive.

At the young age of 22, the former host of X Factor who has already had her shares of ups and downs, looked fab as she officially debuted her sweltering new single Cool for the Summer on iHeartRadio with an exclusive poolside performance on Gansevoort Park Avenue’s sky-high rooftop.

Dressed in a skimpy black top and knee-high gladiator stilettos, Demi, who dates Wilmer Valderamma, arrived ready to celebrate summer with a flock of blow up flamingos and pool floats.

After rousing the crowd with an electric performance, Demi slid off her cutoff jean vest and leaped into the pool full of her fans to mingle and snap countless selfies.

Sounding already like a summer anthem, the song will be featured on her forthcoming album, and arrives just in time for fourth of July.
