New York rapper 50 Cent is taking his Floyd Mayweather Jr. beef to an all-new level. The hip-hop star has moved from kiddy jokes to now full-blown accusations involving murder.

Fif went to Instagram last night (July 23) and claimed Floyd’s thirst for married women ultimately cost a woman her life.

Back in December 2014, reports emerged about Floyd allegedly going on FaceTime with his friend Earl Hayes shortly before his murder-suicide.

TMZ broke the story … 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)

Yesterday, Floyd Mayweather offered to pay people real money in exchange for trolling 50.

A few hours prior, 50 Cent claimed Floyd might low-key be lying about his wealth.
