Justin Bieber and Floyd Mayweather have had a huge falling out, with the pop star reportedly "distancing" himself from the boxer.
Sources told TMZ Bieber was reassessing his friendships and wanted to "reset boundaries" with Mayweather.

And the boxer did not take it well, going "insane, nuclear" and calling Biebs a "traitor."
The Despacito singer unfollowed Mayweather on Instagram, a move that has left Mayweather incensed ahead of his fight against Conor McGregor in Las Vegas this weekend.
