"It is with deep sadness to inform you that we lost a true icon, a real life superhero. Joanie Laurer aka Chyna, the 9th wonder of the world, has passed away," said a post on her website.

After graduating from the University of Tampa, Chyna started training in the world of professional wrestling and in 1996 she was named the "Rookie of the Year for the Women's Championship," according to her website. She wrestled in the Royal Rumble and King of Ring tournaments and became the only undefeated Women's Champion in WWF (World Wrestling Federation) history.

"Thoughts and prayers go out to Chyna's family. She was always cool with me. #Rip9thWonder," wrote wrestler James Storm on Twitter.

Stephanie McMahon of WWE (World Wrestling Entertainment) posted "She was truly a pioneer in our industry, and she will be missed. #RIPChyna."

Chyna also appeared in TV, magazines, music videos and in adult films. Her 2001 autobiography is titled "If They Only Knew" and calls her "part feminist, part superhero, Chyna blazed a trail where no woman had gone before."
