Floyd Mayweather told TMZ Sports this week that he would be just the guy to promote the Justin Bieber and Tom Cruise fight!
There has been serious talks of setting up a fight with the pop singer and movie legend after JB tweeted about it last month.
Dana White has said he'd be down to make it happen and predicts it would be the biggest fight in UFC history.
"If they bring me in as a promoter, then I can talk about it. But until then, I gotta stay in my lane. Gotta stay in my business."
Remember, Mayweather used to be super tight with Justin Bieber -- he even let the pop star walk him to the ring for a few of his fights. Floyd even trained Bieber to box at one point.
