OK, now this thing between what was once thought as a friendly game of the dozens has just gotten real.

50 now alleges that Money Mayweather’s thirst for married women cost a woman her life back in 2014 in a murder-suicide involving Fif’ homie Earl Hayes.

In December of 2014, Floyd Mayweather Jr. was on FaceTime with his longtime friend before he ultimately killed his wife Stephanie Moseley and himself.

Floyd urged Hayes to leave his wife because she was bad for his career, but reports have surfaced that he was overcome with grief over what he believed was repeated infidelity.

Floyd was on FaceTime with his rapper friend Monday morning when the shots were fired. Now we’re told, Floyd was telling Hayes he should leave his wife, Stephanie Moseley — a well-known backup dancer and star of VH1’s “Hit the Floor” — because she was bad for his career. As we reported, Hayes was distraught over what he believed was repeated infidelity, including a fling he said Stephanie had with Trey Songz. (TMZ Sports)

These two have been going at it over the past week, from Mayweather accusing 50 of not being as rich as he says he is and Fif doing a hilarious job of accusing Money of being illiterate.

So far, 50 Cent 15 Love.
