Noah Cyrus hops on the back of a jet ski with fellow singer on Saturday (July 15) in Miami, Florida.
The 17-year-old singer kept things cool in a white T shirt while Austin went shirtless after they hit the water.
Noah and Austin are in town to perform at the Y100′s Mac-a-palooza Pool Party.
Earlier that day, Noah hit the stage with Austin‘s ex Becky G to perform at the festival.
