Floyd Mayweather is clearing up the rumors about a possible boxing match with UFC star Khabib Nurmagomedov -- telling TMZ Sports, "Oh, we fighting!"
"I'm my own boss," Floyd said in Bev Hills ... "So, I can't say what's going on on Khabib's end. But, on my end, we can make it happen."
Of course, Khabib and his manager called out Floyd after dominating Conor McGregor at UFC 229 ... though it was unclear if they wanted a boxing match or an MMA fight.
