Ozzy Osbourne has admitted that he began his battle with alcoholism as a teenager.

The legendary hellraiser insisted that his parents never warned him of the dangers of alcohol and drug abuse.

He told Heat: "I started drinking as a teenager. Even then I never liked the taste, but I f**king loved the feeling. Looking back, I was drinking alcoholically even then.

"My parents never told me about sex, drugs, drinking, smoking. I just thought drinking what was what you did."
