Justin Bieber shows off his toned shirtless body while walking along the dock on Sunday (June 14) in Miami, Fla.

The 21-year-old singer was joined for the sunny day out by his friend Hailey Baldwin and they were seen going for a fun jet ski ride together. Justin wore a pair of Calvin Klein underwear under his jean shorts and the briefs became a bit see-through after getting wet!

Justin and Hailey were also seen hanging out by the pool with pals earlier in the day.
