Ozzy Osbourne refuses to read his wife SHARON's recently released autobiography, because he can't bring himself to relive the pain he has put her through.

The rock manager's cancer battle and her many bust ups with Ozzy - he was once arrested for attempting to murder her while drunk - are all included in the pages of Extreme.

He say, "I won't read it. It just f**ks me up. I've done some pretty bad things."
