Richard Simmons says dehydration is the reason for his recent hospital stay.
USA Today reports the 67-year-old fitness guru said in a statement through his publicist Sunday that he was "dehydrated and needed some fluids" and that he's now "feeling great!"
TMZ had reported Friday that Simmons had been hospitalized.
The New York Daily News reported in March that friends of Simmons told the newspaper that they feared he was being held captive at his home by his live-in housekeeper.
Simmons responded to the report by explaining to "Entertainment Tonight" that he was purposefully staying out of the public eye saying, "this is how I want to live my life right now."
"No one is holding me in my house as a hostage," Simmons told NBC's Savannah Guthrie in a phone interview in March.
He rejected concerns by friends that he is being kept at home at his Hollywood Hills mansion, perhaps by his long-time housekeeper, according to the Daily News.
