The popular wrestling personality and actress known as Chyna was found dead three days after she posted a “rambling and sometimes incoherent video” on YouTube, the Los Angeles Times reports. (Watch the video below.)

“In the 13-minute video posted to her YouTube channel on Sunday, a groggy Chyna, whose real name was Joan Marie Laurer, walks around a beach-side residence talking to herself,” the Times reports. “She wears headphones and feathers in her hair and speaks in slurred language as she makes herself a smoothie and talks about the vitamins she’s taking.”

Chyna was found dead in her Redondo Beach, Calif., apartment Wednesday afternoon, officers said. They responded to the apartment after receiving a call from a friend of Chyna’s about a woman not breathing. Chyna was 46, although some media outlets are reporting her age as 45.

In a statement, the police department indicated that the friend said Chyna had not answered her phone in a few days. The statement notes: “From the preliminary investigation, it appears that the deceased passed away prior to being discovered by the friend.”

The Times adds: “The cause and time of Chyna’s death is under investigation by the Los Angeles County coroner’s department. There were no signs of foul play, police said.”

Chyna became a big part of the World Wrestling Federation in the late 1990s, being billed as the “Ninth Wonder of the World” after wrestling star Andre the Giant had become known as the “Eighth Wonder of the World.” She often wrestled against men, and held the WWF Intercontinental Championship twice, along with winning the WWF Women’s Championship. She was an original member of the wrestling group known as D-Generation X.

Laurer appeared in a number of TV shows, including a guest spot on “3rd Rock from the Sun” and a hosting gig on “Robot Wars: Grand Champions.” She was a cast member on “The Surreal Life” in 2005.

She also had a career in porn, starting in 2004, and had roles in movies, including “Illegal Aliens,” along with being featured in video games and modeling in Playboy. Her autobiography, “If They Only Knew,” came out in 2001.
