A rapper and his wife were found dead in their Los Angeles apartment Monday, and a famous boxer Floyd Mayweather Jr. allegedly witnessed the couple's demise via an iPhone video chat. 

Fox News reports 34-year-old rapper Earl Hayes, son of Isaac Hayes, and 30-year-old Stephanie Moseley, Hayes' wife and star of VH1 series, "Hit the Floor," were found dead on Monday.

The Los Angeles Times reports that on Monday, Los Angeles police received calls around 7:30 a.m. that gunshots and a woman screaming were heard in an apartment in the 300 block of Hauser Boulevard in the city's Fairfax neighborhood. Police arrived finding a barricade situation and summoned SWAT officers.

When SWAT officers arrived, additional gunshots were heard. Officers rushed into the apartment where they found Hayes' and Moseley's bodies.

Burrel Wilks, Hayes' best friend, confirmed the news to the press outside the couple's apartment Monday.

"No one seen this coming -- because, again, Hayes is not a violent guy," Wilks told KTLA. "We're all devastated. We're at a loss for words on this one."

During his music career, Hayes was once signed to boxer Mayweather Jr.'s record label. The two became good friends and were often seen partying together. According to TMZ, Hayes called Mayweather on FaceTime Monday morning upset that Moseley had been unfaithful and threatened to kill her. Mayweather reportedly pleaded with him not to, but Hayes pulled out a gun, shot Moseley and then killed himself.

According to KTLA, Moseley's friend Eva Marcille Pigford said the couple had no known history of violence, but rather "typical relationship issues" that would not have led to violence.

"Stephanie was an absolute angel. She really was," Pigford said. "She brought so many people into my life. She's connected so many people. She's just loved. She will never, ever, ever, ever be forgotten."

Moseley became a reality TV personality on the VH1 series "Hit the Floor." Prior to that, she was a backup dancer for Chris Brown, Britney Spears and other performers.

Autopsies for Hayes and Moseley aren't expected for another day, a Los Angeles County coroner's official told the Los Angeles Times.
