The 22-year-old pop star, who has been a brand ambassador for the underwear line since last January, also shared a snap of himself hanging out at a pool with Martin Garrix. The DJ/producer is currently in Las Vegas to perform a set at the OMNIA nightclub as part of a Memorial Day Weekend lineup.

Calvin Harris was also scheduled to perform but had to cancel as he is still recovering from the injuries he sustained in a car accident last week, which briefly landed him in the hospital.

"He has asked us to pass on his apologies to everyone who was due to attend the shows and hopes to be back to his normal schedule soon," a statement on Harris' official Facebook page read.
