Justin Bieber Gets in the Ring With Floyd Mayweather

Justin Bieber has finally found an appropriate activity to do shirtless. The 20-year-old singer hopped in the ring with Floyd Mayweather for some boxing lessons on Thursday night.

“Training with the Champ @FloydMayweather tonight,” the Biebs casually posted on his Vine account. The short clip showed the undefeated boxer holding up some pads for the pop star to swing at. Floyd even gave his pal a nickname… “money bags.” Adorable.

“Training and having a good time with @justinbieber,” the 37-year-old tweeted after the lesson.

In May, the “Confident” crooner (and Lil Wayne) escorted Mayweather to the ring for his fight against Marcos Maidana. Bieber is frequently seen at Floyd’s boxing matches with their friendship dating back to 2012. Apparently, Floyd’s daughter is a fan of the singer.

Mayweather’s former pal 50 Cent actually explained the Justin-Floyd connection to MTVtwo years ago.

“Justin is also a Floyd fan,” the rapper revealed. “They love the sport. A lot of people like it and haven’t actually made contact or received anything to make them feel like it was cool or comfortable enough for them to come. When it actually happens and it goes down like that, it feels good. When they get a chance to see different genres, different people, everybody’s excited. Floyd’s daughter, Yaya, she saw half the fight, the other half she was looking at Bieber.”

Fourteen-year-old Iyana’s Twitter avatar is even a photo of her and Justin.

So… who do you think the Biebs was thinking about when he was throwing those punches?
