“@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.”

Sean Kingston lays the charm on Brenda Song in this behind-the-scenes look at the upcoming The Suite Life on Deck episode, “Party On.”

The 20-year-old R&B singer shares in the video, “The party scene was fun. It reminded me of a music video that I’d do, with singing to London and everyone dancing and having a great time.
