Ozzy Osbourne says Sharon Osbourne suffered "Exorcist"-like seizures during her treatment for cancer.

He explained: "Sharon is the strongest woman I know. When I saw the scans of the colon, I thought, 'No way'. The cancer was so aggressive.

"She had three chemotherapies a month and after nine months the side-effects got worse and worse.

"She was having seizures - she was like The Exorcist, bouncing around the bed. I thought I was going to lose her.

"I thought it was all going to be too much for her. Then at the end of the nine months the doctor said, 'She's going to need nine months to get over the chemotherapy'. Her response was, I'm cancer free, great. I'm going shopping'."

However, despite 62-year-old Sharon - who had a double mastectomy in 2012 after learning she carried a gene that increased her risk of developing breast cancer - having won her battle against the disease, Ozzy, 65, is still worried about losing his wife.

He told The Sun newspaper: "I go to AA [Alcoholics Anonymous] meetings at a place close by every lunchtime. I didn't want to but I had to if I wanted to keep my family.

"It's hard. I had a therapist at first but that didn't work so I agreed to try AA."

Ozzy - who is now 19 months sober - added: "Alcoholism is an illness. I don't like going to the meetings but if I don't go I know I will drink again. And I worry about losing everything, so I just don't want to drink anymore."
