Apparently, Mayweather is big fan of The Biebs because the singer is going to get to walk out with the boxer at his next big match!
This Saturday, Mayweather is slated to fight Saúl "Canelo" Alvarez at the MGM Grand, and the pop star will be at his side.
And in case you didn’t know, Mayweather even flew Bieber out to sing at his daughter’s 13th birthday party.
