A shocking new allegation made by a podcast is claiming Richard Simmons a prisoner in his own home. Missing Richard Simmons is the No. 1 podcast in America and is produced by the exercise guru's close friend, TV producer Dan Taberski. It has been 1,000 days and counting since Simmons was last seen in public, and three years since he walked away from his life as America's most outrageous work-out guru. In that time, he's apparently shut himself away in his Hollywood mansion.
