The 70-year-old is said to have been filming a paranormal TV show in California before being taken to hospital.
According to TMZ, Sharon ‘suffered a terrifying medical emergency’ and fell ill while on set.
Ventura County Fire Department also confirmed to the publication that EMS workers responded to a ‘medical call’ on Friday evening and transported a patient to hospital, who was later confirmed to be Sharon by Santa Paula Police Chief.
Sharon has been looking after her husband Ozzy Osbourne, 73, over various health battles, having lived with Parkinson’s disease since 2003, and undergoing multiple spinal surgeries for a fall he suffered in 2019.
Sharon, who married Ozzy in 1982, recently celebrated her 70th with a lavish bash, in which she spent the night slow-dancing with her rocker husband, at the star-studded event with pictures showing the couple’s children Kelly and Jack Osbourne all dressed up for the 20s themed party.
