Kylie is so rock'n'roll. In her 16-year reign she has pooh-poohed every rule in the pop realm, yet still has her tiny bowling-ball booty parked firmly on the throne. Quit while you're ahead? Don't accept film roles in video game spin-offs (Streetfighter, for instance)? Never be photographed wearing a brim-only hat with your perm poking out at a jaunty angle? Pah! Such maxims mean nothing to Kylie.
