Floyd Mayweather Wants to Promote Justin Bieber vs. Tom Cruise Fight

Every blockbuster fight needs a big-time promoter … and Floyd Mayweather tells TMZ Sports he’s the guy for Justin Bieber‘s potential fight against Tom Cruise!!

As we previously reported … there have been serious talks about setting up a fight between the 25-year-old singer and the 57-year-old movie superstar after Biebs playfully tweeted about wanting a piece of TC last month. 

Dana White — who was tagged in Bieber’s initial post about the dream fight — has said he’d be down to make it happen and predicts it would be the biggest fight in UFC history.

Enter Mayweather — who says he wants NOTHING to do with training either celeb for the possible fight … but wants EVERYTHING to do with the money involved.

“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.  

But, the two had a falling out back in 2017 … and haven’t really spoken since. 

Floyd didn’t back Justin when we spoke with him … but he didn’t exactly praise him either.
