English singer Amy Winehouse has hit back at rumours Kelly Osbourne is a bad influence on her - insisting the reality star has saved her life. According to British newspapers, Winehouse cut short a recent UK gig (06JAN07) to be sick after spending the day drinking with Osbourne. However, Winehouse praises Kelly - the daughter of SHARON and Ozzy Osbourne - for keeping her on the straight and narrow. She explains, "Kelly is like my conscience telling me when I've had enough. "Without her I'd probably be dead."
