The site's sources claim Hayes had called Mayweather on Monday morning "in a rage" about allegations that Moseley had cheated on him. Mayweather reportedly begged Hayes to calm down and not act on his anger. TMZ reports that Mayweather remained on the phone as Hayes allegedly killed his wife and himself.

Later that morning, Hayes, whose father was soul legend Isaac Hayes, and Moseley, the star of VH1's cheerleader series "Hit the Floor," were found dead together by a SWAT team in what appeared to have been a murder-suicide. Neighbors reportedly said they heard gunshots coming from the couple's home.

TMZ reports that Mayweather "will not say how much he saw, but he acknowledges he was a witness and heard everything."

The Los Angeles Police Department is currently investigating the deaths, while the Los Angeles Coroner's Office expects to have completed autopsies in another day or so, according to the Los Angeles Times.

Moseley, once a backup dancer for Chris Brown and other major artists, was remembered warmly on social media and in the press Monday. Burrell Wilks, who said he was Hayes' best friend, told KTLA he was "devastated" because Hayes "was not a violent guy."

Brown memorialized his late friend and former dancer on Instagram, writing, "RIP baby girl. Danced with me on tour and was always the coolest person. My prayers go out to you and HAZE family."

According to GossipCop, Hayes believed Moseley had an affair with Trey Songz.
