Rock star Ozzy Osbourne described the success of the reality TV show about his family as "terrifying", in an extract from his memoirs published today.
The former Black Sabbath frontman, 60, said appearing in the MTV series 'The Osbournes' was like being "strapped to a rocket and being blasted through the stratosphere at warp factor ten.".
His memoirs, called 'I Am Ozzy', describe his early success with rockers Black Sabbath, his marriage to Sharon and his battle against drink and drugs.
Ozzy Osbourne, who grew up in Birmingham, England, worked in a factory before finding fame in the pioneering heavy metal band.
He was eventually kicked out of Black Sabbath in 1979 and launched a solo career and moved to the United States.
The Osbournes also made celebrities out of his wife Sharon and children Jack and Kelly who featured prominently in the show filmed at the family's Los Angeles home.
In his memoirs, extracts of which are published in The Times, Osbourne describes the infamous incident when he bit the head off a bat during a concert thinking it was a rubber toy.
He said: "Immediately, though, something felt wrong. Very wrong.
"For a start, my mouth was instantly full of this warm, gloopy liquid, with the worst aftertaste you could ever imagine. I could feel it staining my teeth and running down my chin.
"Then the head in my mouth twitched."
'I Am Ozzy' is published on October 1.
