SIR Elton John became hooked on cocaine because it gave him the confidence to be a rock star. The singer revealed the extent of his drug abuse for TV show Elton John: Me Myself and I, which aired in the UK on Saturday (22Sep07). The Rocket Man star claimed he was too shy to handle his fame until he was introduced to the drug in the 1970s: "It gave me the confidence to join the game. But I wasn't the kind of person who would do one or two lines. I did a gram and then called out for more." But the drug caused John to meltdown. Besides almost killing him, he confesses it turned him into a detached and demanding diva, adding on the show, "I was once staying in a hotel in London and it was really windy outside. I rang up the office and asked if there was anything they could do about it. That's how bad it got."
