Legendary fitness guru Richard Simmons died on Saturday, according to a report.
He turned 76 on Friday.
TMZ first reported his death. His housekeeper contacted police just before 10am, according to the outlet.
Simmons was pronounced him dead at the scene. His cause of death is not immediately known and has not been announced.
On Friday, he thanked his fans who wished him a happy birthday on social media.
The news comes months after he revealed in March that he was diagnosed with skin cancer.
“I sat in his chair and he looked at it through a magnifying mirror. He told me he would have to scrape it and put it under the microscope. Now I am getting a little bit nervous,” the fitness personality wrote at the time. “He comes back about 20 minutes later and says the C word. ‘You have cancer.’ I asked him what kind of cancer and he said, ‘Basel [sic] cell carcinoma.’ I told him to stop calling me dirty names. He laughed.”
Simmons became a fitness sensation in the 1980s shortly after he opened a fitness studio, called The Anatomy Asylum before being rebranded as Slimmons, in Los Angeles.
The TV fitness pioneer became known for his regular appearances on TV and radio talk shows, including the Late Show with David Letterman and The Howard Stern Show, and for his popular series of aerobic videos Sweatin’ to the Oldies.
His workouts launched his celebrity status, leading to further film and television appearances, including General Hospital, The Larry Sanders Show and Arrested Development.
But the on-screen instructor, identifiable by his workout tank tops and short shorts, disappeared in recent years, worrying fans.
He hadn’t made a public appearance since 2014 — prompting him to a give phone interview to The Today Show in 2016 to put to rest rumors that he was being held hostage by his housekeeper.
