Demi Lovato celebrated the release of her new summer anthem in New York on Wednesday (01Jul15) by diving fully clothed into a swimming pool full of screaming fans.
The pop star performed her new song Cool for the Summer live for the first time at a pool party fan event hosted by New York's Z100 radio station and concluded the rooftop gig at the Gansevoort Park Avenue hotel by taking a dive into the water.
Wearing a tattered denim outfit, fishnet stockings and high heels, Lovato was a treat for many fans who had no idea their pop idol would be at the party, let alone in the pool next to them, posing for selfies.
She wasn't wet for long - security guards pulled her out of the rooftop pool after just a few minutes and wrapped her in a bathrobe.
Lovato then headed inside the hotel for a scheduled question-and-answer session with her pool pals and other waiting fans.
The party was the first of many summer-themed launch bashes Lovato is hosting for fans across America.
