Did Floyd Mayweather rile up rapper friend about his 'cheating wife' before he shot her dead and killed himself?

Floyd Mayweather allegedly riled up his rapper friend Earl Hayes over his wife's infidelity before Hayes gunned her down in the bathtub and then killed himself, according to a new report. TMZ claims that the champion boxer told his rapper friend over iPhone FaceTime Monday morning that he was 'weak' for not leaving Stephanie Mosley after she allegedly cheated on him with a fellow rapper. Citing anonymous sources, TMZ says that Mayweather was still on FaceTime when Hayes left to get a gun.

A message MailOnline left with Mayweather's publicist was not immediately returned. Realizing that his friend was out of control, Mayweather pleaded for Hayes to calm down and stop what he was doing. According to a source who spoke to TMZ, '[Mayweather] was pleading with him to get a grip ... to no avail.'

The source added that Mayweather will not say how much he saw, but he acknowledges he was a witness and heard everything. A message MailOnline left with Mayweather's publicist was not immediately returned. While the prize fighter was still on the phone, Hayes allegedly went into the bathroom and fired 10 to 12 shots at his wife, who was taking a bath.
