Hugh Hefner responds to reports that he is dying

Playboy founder Hugh Hefner has slammed reports that he is unwell. Many reports were making rounds that he is extremely sick.

The 90-year-old took to his Twitter account to clear the rumours. He tweeted: "I wish the tabloids had informed me a little earlier in the week that I'm sick. I might have cancelled my weekend plans."

Adding on, he also posted a picture with his wife, American model/television personality Crystal Harris. He wrote: "Tonight's Mansion movie is the classic western, 'Shane.'"

According to ET, Hefner's health is fine. A source said: "It's no secret that over the past few years he has suffered with back pain that has made it a bit more challenging for him to get around, but at 90 years of age, he is enjoying his life, and is still very involved in the day-to-day activities of editing the magazine."

Previously, Harris had revealed that she does not notice the 60-year age difference between her and Hefner. She told Access Hollywood: "Hef's very romantic, very cozy. We really care about each other and get along great. I don't notice the age difference. Hef's a lot of fun."
