Floyd Mayweather wants to promote Justin Bieber against Tom Cruise Fight

Every blockbuster fight requires a big promoter … and Floyd Mayweather recounts TMZ Sports he's the guy for Justin Bieberthe potential of fighting Tom Cruise!!

As we had previously announced, there was serious talk of organizing a fight between the 25-year-old singer and the 57-year-old film superstar, after Biebs tweeted playfully about wanting a piece of TC last month.

Dana White – which was tagged in Bieber's initial post about the dream fight – said that he would be in place to get there and predicted that it would the biggest fight in the history of the UFC.

Enter Mayweather – who says that he does NOT want to do anything with celebrity training for possible fighting … but wants everything to do with the money involved.

"If they make me come as a promoter, I will be able to talk about it, but by then, I have to stay in my way, I have to stay in my business."

Remember, Mayweather used to be very tight with Justin Bieber – he even let the pop star guide him to the ring for some of his fights. Floyd even Bieber trained at the box at one point.

But, both had a quarrel back in 2017 … and I have not really spoken since.

Floyd did not support Justin when we spoke to him … but he did not congratulate him either.
