Floyd Mayweather Jr., 50 Cent end business relationship; friendship appears over, too

Well, it's official, boxing and hip-hop fans.

Floyd "Money" Mayweather Jr. and 50 Cent are BFFs no more. Or money mates, for that matter.

This business and best-friends relationship is history, as has been rumored for several weeks. Mayweather and Jackson had formed TMT Promotions ("The Money Team") while Mayweather was in jail last summer. But while it got licensed to promote fights in New York, it never got off the ground.

And 50 Cent, whose real name is Curtis Jackson, left no doubt about it, tweeting Thursday that "TMT IS OVER the money team is no longer a team. So it SMS promotions that's it thats all.SMSaudio"

And just to rub a little salt in the breakup wound of TMT, Fitty announced that his SMS promotions would put the Yuriorkis Gamboa vs. Miguel Beltran fight on the undercard of the Manny Pacquiao-Juan Manuel Marquez fight at the MGM Grand on Dec. 8.

That's notable because that Dec. 8 card is promoted by Top Rank, which is run by Bob Arum, who has become a hated enemy of Mayweather. Arum once represented Mayweather, and the two haven't had a civil word in a while.

Mayweather has been represented in fight negotiations by Golden Boy, which has been involved in a "cold war" with Top Rank for several years.

Gamboa had been with Top Rank but became friendly with Mayweather and signed with TMT. Now he's back in Arum's good graces.

Fitty also tweeted this: Catch IBF CHAMPION BILL DIBB VS. JASON VELEZ DEC.1 (Miguel) Cotto's card lets go New York!!! Don't miss it"

The rapper intimated that Mayweather wasn't the money man he purports to be. "I move the fighters to SMSpromotion cause the other half of the money team .Didnt put up there $MONEY$.SMSaudio," he tweeted.

And one last turn of the knife: "If anyone wants a money team jacket I'm selling mine for a dollar. The nap back hat comes with it. That's a fare price. SMSaudio."

Yup. Love is (MGM) grand, ain't it?
