The relationship between 50 Cent and pound-for-pound king Floyd Mayweather Jr. is over.

The breakup, rumored for weeks, was announced by 50 Cent on Twitter on Thursday. It means featherweight titlist Billy Dib, one of the fighters who 50 Cent signed, will make his next defense on the undercard of Miguel Cotto's fight against junior middleweight titleholder Austin Trout on Dec. 1 (Showtime) at Madison Square Garden in New York.

50 Cent, whose real name is Curtis Jackson, announced during Mayweather's two-month summer incarceration for domestic abuse that he had formed TMT Promotions, which is short for "The Money Team" and is what Mayweather calls his entourage. 50 Cent and Mayweather were going to promote fights together, and 50 Cent also strongly hinted that the company would promote Mayweather's fights instead of Golden Boy Promotions, which has been promoting Mayweather's events since 2007.

TMT Promotions was licensed by the New York State Athletic Commission in July, and 50 Cent signed multiple fighters, including undefeated former unified featherweight titleholder Yuriorkis Gamboa, Australia's Dib, and super middleweight contender Andre Dirrell.

But 50 Cent said that he and Mayweather are no longer working together, tweeting, "TMT IS OVER. The Money team is no longer a team. So it's SMS Promotions. That's it. That's all."

SMS Audio is the name of 50 Cent's headphone product line.

50 Cent also tweeted, "I'm no longer a part or down with TMT Promotions. If anyone wants a Money Team jacket I'm selling mine for a dollar. The (snap) back hat comes with it. That's a (fair) price.

"Get your TMT sweat suit NOW!! For just $7.99 online No shipping and handling. I move the fighters to SMS Promotions 'cause the other half of the money team didn't put up (their) MONEY$."

Leonard Ellerbe, one of Mayweather's advisers, could not be reached for comment.
