The unlikely pairing of pals Floyd Mayweather Jr. and Justin Bieber just keeps getting unlikelier.
The undefeated "Money" Man now apparently is tutoring the pop star in Mayweather's sport.
Images shared online -- some via a tool called Shots that Mayweather and Bieber have invested in -- show Bieber in the ring working on his boxing with Mayweather in the trainer's role.
And here it is via Vine, with Bieber throwing punches and Mayweather catching them.
The two have been hanging out together for a while, with Bieber a visible presence at Mayweather's fights, including recent matches with Marcos Maidana and Saul "El Canelo" Alvarez. In fact, before the May bout with Maidana, Biebs posted an Instagram of him and Mayweather enjoying a massage and pedicure together.
So should we be surprised that Mayweather is showing Bieber the ropes? After all, after a couple of bros share a spa day, isn't the next logical thing to lace up the gloves?
