The 63-year-old star - who has reportedly split from the Black Sabbath rocker over allegations he had an affair with a celebrity hairstylist - has broken her silence on social media.

She wrote on Twitter: "Huge thanks to everyone that has been so supportive to me with kind words & wishes. I wish their was another word I could use than thank you."

Meanwhile, Sharon - who has Kelly, 31, Aimee, 32 and Jack, 30, with Ozzy - addressed her split from Ozzy when she appeared on 'The Talk' on Tuesday (10.05.16).

She said: "I'm 63 years of age, and I can't keep living like this ... I've been avoiding looking at any pictures or reading anything. I know what's going on. I don't need to read about or see about it. It's like putting salt in a wound. I don't need to ... He's back, and now I'm out of the house."

And the 67-year-old singer - who has been married to Sharon since 1982 - previously denied rumours he had suffered a relapse.

He said: "I have been sober for three and a quarter years. I have not touched drugs or alcohol in that time. Any reports that I am not sober are completely inaccurate."

Sharon is said to have gone "ballistic" after she allegedly found out he had an affair.

A source said: "Sharon went ballistic with Ozzy and accused him of having the affair. She said she had suspected something had been going on for some time and now had proof.

"People are wondering whether Sharon went through Ozzy's phone before accusing him. She has done that before but in the past she was checking if he'd been using drugs. Ozzy was extremely sheepish and admitted being close to Michelle. It is likely Sharon has discovered calls and possibly meetings.

"He is not speaking to Sharon and she has not let him back into the house. Ozzy went straight to the Beverly Hills hotel which is very near their home. He is well known there and has been there before when they've had rows."
