Pop star Pink has lavished praise on her chart rivals Lily Allen and Amy Winehouse for keep pop unpredictable. The outspoken singer is delighted her British counterparts aren't afraid to spice up the industry with booze, drugs and raunchy behaviour. She says, "Amy and Lily are going crazy in America right now. I think they're awesome. "I'm very excited about them. Sex and drugs are an integral part of being a rock star. It's all about your attitude and how you do your thing. "Having the experience of sex and drugs is a good thing but you don't have to continue. It's more important who you are and what you stand for."
