The TV personality had already undergone five cosmetic surgeries but has now decided that enough is enough.
She described feeling "frightened" after her most recent facelift, which "put me off" having any further procedures.
"Time is against me, I cannot have another facelift," she told The Sun. Her husband, Ozzy Osbourne, reportedly offered to pay for corrective surgery.
Sharon has always been open about her cosmetic surgery, including a procedure to lift up her mouth, which she discussed with Kelly Clarkson in 2019.
However, even after the surgery, she struggled to feel her mouth and described it as being "numb and it was up on one side."
In addition, Sharon suffered a medical emergency at the end of last year, which left her unconscious for 20 minutes.
