Richard Simmons is blasting a news report claiming the fitness guru is transitioning into a woman.
Simmons' rep called the story in the National Enquirer "absolute madness and not true."
The Enquirer claims Simmons has received breast implants and hormone treatments over the last 2 years and is becoming a woman. The report claims he's now "a softly spoken woman named Fiona."
Simmons went into virtual seclusion almost 3 years ago, shutting out friends and family. He claimed he wanted a break from the spotlight and was struggling with a bum knee.
TMZ broke the story ... Richard was hospitalized Friday night and stayed at Cedars in L.A. until Monday.
We got this pic of him sporting a beard in the backseat.
