Former WWE world champion Bret "the hitman" Hart says he has cancer.
The wrestler shared the news to his thousands of followers on Instagram.
One of WWE's most popular former superstars, he posted: "I openly declare myself in my fight against prostate cancer."
In a long message he went on to say that he wants to set an "example for men everywhere who find themselves in my very same shoes".
Famous for his leather jacket, sunglasses and pink spandex Canadian Bret Hart was inducted into the WWE Hall of Fame in 2006.
He famously fell out with WWE boss Vince McMahon in 1997 before returning to the company years later.
He says he will now have surgery in the coming days.
Posting on Instagram he said: "My fans have always looked upon me as a hero and I've always done my best to live up to that in and out of the ring.
"I will wage my fearsome fight against cancer with one shield and one sword carrying my determination and my fury for life."
Bret Hart was much loved by fans because of his charisma in the ring and his punishing finishing move the Sharpshooter.
The Hitman comes from a wrestling family. His father Stu Hart is also a member of the WWE Hall of Fame.
His brother Owen Hart was also a WWE wrestler but died controversially after an accident during an entry to the ring in 1999.
Bret Hart's catchphrase as a wrestler was "the best there is, the best there was and the best there ever will be".
He now says his next fight is to show that "prostate cancer can be beaten".
