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.
