"I don't drink, never, and I don't smoke and don't do drugs," the family-and career-minded superstar once said. "I never started drinking or smoking. When I was little, my mother drummed it into me how bad it is for you, and it stuck somehow. My little sister also doesn't drink or smoke. Everybody knows smoking is bad for you, and drinking [is bad] as well. I don't need to drink to have a good time."
