Justin Bieber took a break from banging Hailey Baldwin to perform at Leonardo DiCaprio's New Year's Eve bash in St. Barth last week. And of course things got hot on the Caribbean island -- so Justin had to whip his shirt off during the performance! Typical Bieber!

Photos just emerged of the "Sorry" singer performing shirtless on Leo's luxury yacht in the Caribbean. The Biebs delighted fans with a rousing performance around the stroke of midnight, Billboard reports.

The publication says that the 21-year-old asked the crowd, "Who is representing New York? Who wants to have a good new year? Who has a good year resolution? Who was once not a Belieber, and is now?"

Apparently the superstar singer asked the audience to put their phones away a soon as he started singing his latest hit "Sorry."

In addition to JB, Machine Gun Kelly also performed for the fine young things at the bash. Robin Thicke, his girlfriend April Love Kate Middleton's brother James Middleton were also in attendance, reports Billboard.
