Justin Bieber wears just a pair of white Calvin Klein boxer briefs while wakeboarding on Sunday (July 3) in Miami, Fla.

The 22-year-old singer’s underwear became totally see-through after getting soaked in the water! He was joined on a yacht that afternoon by his good friend Ryan Good and his longtime girlfriend Ashley Benson.

Justin was also seen in a pair of green trunks and an orange swimsuit throughout the weekend. He is in town for stops on the Purpose Tour!
