Elton John admits that he did not practice safe sex during his drug addiction when the AIDS epidemic began in the 1980s. The rock singer revealed personal details of his life in an upcoming exclusive interview with "Today" show host Matt Lauer. "When you take a drug and you take a drink and you mix those two together, you think you're invincible," John tells Lauer. "I came out of this HIV negative... I was the luckiest person in the world."
