Hellraiser Ozzy Osbourne once broke his wife SHARON's two front teeth during an alcohol fuelled argument, after she hurled a bottle at his head.
The rock matriarch reveals the violent truth behind her turbulent marriage in her new autobiography EXTREME - but insists she had her revenge.
She writes, "We were both drinking heavily, though I hated the stuff and was only doing it to keep up with him.
"One time I threw a full bottle of scotch and it hit him on the back of his head.
"He turned, came charging back and hammered me against the wall so violently that my two front teeth broke off.
"I smashed his precious gold discs, including the first gold for THE BLIZZARD OF OZ album. Ozzy called me psycho woman."
