Osbourne, 61, has been married to the 58-year-old former X Factor judge for 28 years and they have three children together – Kelly, Jack and Aimee.
The former Black Sabbath frontman was previously married to wife Thelma and he adopted her son Elliot, as well as having two children – Jessica and Louis – with her.
Writing in his Ask Dr Ozzy column for The Sunday Times magazine, he said: 'At one point, I was spending so much time juggling between my first wife, Thelma, and my second wife, Sharon, I'd come home and call the missus 'Tharon' – which earned me more than a few black eyes, I can tell you.'
