Richard Simmons (pictured here in May 2010) made a surprise appearance on Dancing with the Stars earlier this week to coach Chaz Bono, and the visit has left the fitness guru's fans wondering if he's sick.
The 63-year-old looked gaunt and pale, and his badly dyed hair was definitely thinned out.
His surprising appearance triggered a slew of online commentary about the state of the 63-year-old's health.
"He doesn't look very good to me," wrote one fan on people.com
Another fan writes: "He looks 83."
The concern became so widespread that Simmons's rep felt compelled to issue a statement saying, "He is completely healthy, happy and fit as a fiddle. Everything with him could not be better."
