An LAPD statement said: "Los Angeles Police Department West Bureau Homicide Detectives are investigating an apparent murder-suicide that occurred earlier today in Park La Brea.
"On Monday, December 8, 2014, around 7:30 a.m., Wilshire Division patrol officers responded to a radio call of a shooting in the 300 block of Hauser Avenue. When officers arrived at the apartment complex they heard additional shots being fired. LAPD's SWAT officers responded to the location and discovered two victims inside the apartment suffering from gunshot wounds.
"The initial investigation revealed that 34-year-old Earl Warren Hayes shot his wife, 30-year-old Stephanie Elyse Moseley to death and then took his own life.
"The Los Angeles Fire Department paramedics responded to the scene and pronounced both Mr. Hayes and Ms. Moseley dead at the scene."
Moseley had small roles in films such as Sparkle, Mirror Mirror, Idlewild and Twilight: Breaking Dawn - Part 1. She also carried out stunt work for Halle Berry's 2003 film Catwoman.
Away from the big screen, she featured as a backup dancer on both Britney Spears and Janet Jackson's tours during the 2000s, while she has performed with artists including Beyonce, Jennifer Lopez, Mariah Carey, Rihanna and Usher.
Hayes was signed to Mayweather's label The Money Team.
Neither police nor Mayweather have commented on the TMZ report.
