Richard Simmons has allegedly been hospitalized in Los Angeles after exhibiting ‘bizarre behaviour’. 

Someone from inside his home reportedly called 911 just before midnight on Friday after becoming increasingly worried. 

Paramedics rushed to his home to evaluate the fitness guru and decided the best course of action was to admit him to Cedars Sinai Medical Centre. 

It is uncertain if the 67-year-old is still in hospital. 

Simmons has virtually been a recluse for the past three years, rarely being seen outside his own home. 

His social media accounts have continued to be updated but fans are unsure if it is by him or an employee. 

No mention of the hospitalization has been released.
