The ex-girlfriend of undefeated boxing legend Floyd Mayweather was found dead at her California home, according to reports.

Josie Harris, 40, who had three children with Mayweather, was discovered unresponsive in her car outside her home in Valencia late Tuesday, law enforcement sources told TMZ.

Harris, who had previously accused Mayweather of abusing her on six occasions, was pronounced dead at the scene. Investigators don’t believe there’s any foul play connected to her death, TMZ reports.

Mayweather served time behind bars after a September 2010 incident in which Harris claimed he barged into her Las Vegas home as she slept and attacked her in front of the couple’s children.

Mayweather, who was convicted of misdemeanor domestic battery, spent two months in jail in 2012 for the attack, but claimed he was only found guilty because of his image.

“I’m black. I’m rich. And I’m outspoken,” Mayweather told Katie Couric of the conviction in an interview with Yahoo Global News in 2015. “Those are three strikes right there.”

But Mayweather did acknowledge putting his hands on Harris.

“Did I restrain a woman that was on drugs?” he continued. “Yes, I did. So if they say that’s domestic violence, then, you know what? I’m guilty. I’m guilty of restraining someone.”

Mayweather’s son, Koraun, who was 10 at the time, witnessed the attack and told police he saw his father “hitting” Harris during the incident.

The interview with Couric prompted Harris to file a $20 million defamation lawsuit against Mayweather — a legal fight that was still ongoing, TMZ reports. In September, a Los Angeles judge set a trial date in the case for December, according to The Blast.

Results of an autopsy are still pending, a spokeswoman for the Los Angeles County Department of Medical Examiner-Coroner told The Post. The agency did not formally identify Harris as the victim as of Wednesday afternoon.

Several messages seeking comment from the Los Angeles County Sheriff’s Department were not immediately returned.

The department has confirmed an active investigation into Harris’ death, The Athletic reports.
