Mayweather calls former friend 50 Cent ‘a male boxing groupie’

Floyd Mayweather Jr. and 50 Cent’s friendship and short-lived business partnership is apparently over.

Mayweather took to Twitter on Friday night to rip rapper 50 Cent, his longtime former friend, calling him “a male boxing groupie” and saying his “album sales have declined.”

50, whose real name is Curtis Jackson, started the tweet beef when he repeatedly posted that undefeated boxing prospect Yuriorkis Gamboa, who is not under 50 Cent’s SMS Promotions banner, wants to challenge Mayweather.

“GAMBOA WANTS TO FIGHT FLOYD,” 50 tweeted. “I will put up a extra 20 million for the winner. He don’t like it that Floyd pulled out. #SMSAUDIO”

He added: “You should have know [sic] not to go against me punk.”

Mayweather responded by tweeting that SMS stood for “Snakes Maneuver Slick,” “Sisters Managing Sports” or “Similar Mayweather Show.”

The two were longtime friends and sometimes training partners as 50 dabbled in boxing. In the spring, 50 Cent got his promoter’s license in New York and the two were going to promote fights under the banner of The Money Team. Not anymore.

“TMT IS OVER the money team is no longer a team,” 50 Cent tweeted on Thursday. “So it SMS promotions that’s it thats all.SMSaudio … “I move the fighters to SMSpromotion cause the other half of the money team .Didnt put up there $MONEY$.SMSaudio.”

Fitty announced also this week that SMS Promotions would put Gamboa up against Miguel Beltran on the undercard of the Manny Pacquiao-Juan Manuel Marquez fight in Las Vegas on Dec. 8. That card is being promoted by Top Rank, run by Bob Arum, Mayweather’s chief rival.

Gamboa had been with Top Rank, but became friendly with Mayweather and signed with TMT. Now he’s back in Arum’s good graces and part of 50 Cent’s SMS Promotions, apparently.
