Justin Bieber: Shirtless Time in Miami!

Justin Bieber goes shirtless while relaxing by the pool on Saturday (July 30) in Miami, Fla.

The 17-year-old teen sensation stripped down to his boxer briefs and took a dip in the water while singer pal Sean Kingston relaxed on a lounge chair.

“@seankingston #realfriend” Justin tweeted that same day. “I LOVE MIAMI.”

Biebs has been taking it easy the past few weeks. “I’ve been working so hard, I’m taking a month off,” he told THR last month. “It’s been great to just think and enjoy hanging out with my friends. I’m still growing up, and when you’re working every day, you don’t really get a chance to figure out who you are. So with the time off, I’m able to think, pray and just kind of grow up.”
