MANILA, Philippines - Is WBC welterweight champion Floyd Mayweather Jr. running away from former WBO welterweight champion Manny "Pacman" Pacquiao?

Rapper 50 Cent, who recently dropped out of a business partnership with Mayweather, certainly thinks so. The two traded barbs on Twitter Saturday, November 3.

"I can't hang out with Floyd no more,I'm tired of running from manny pacquiao #smsAudio," 50 Cent tweeted.

Mayweather replied, calling the rapper "a male boxing groupie."

On November 1, 50 Cent announced his separation from The Money Team, his boxing promotions company with Mayweather, to form a company of his own. He then took to Twitter to slam the boxer.

The rapper said: "I move the fighters to SMSpromotion cause the other half of the money team .Didnt put up there $MONEY$.SMSaudio."

Two days after the announcement, 50 Cent challenged Mayweather to take on former Cuban Olympic gold medalist and featherweight title holder Yuriorkis Gamboa.

GAMBOAWANTS TO FIGHT FLOYD. I will put up a extra 20 million for the winner. He don't like it that Floyd pulled out. #SMSAUDIO
