An 18-year-old bodybuilder from Iceland won the 38th Miss World beauty contest Thursday in London. Linda Petursdottir, a 5-foot-7 blonde hotel receptionist, received the $54,000 prize after a panel of judges selected her from among 84 contestants. The first runner-up was Miss Republic of Korea, 22-year-old Yeon-He Choi from Seoul, South Korea. Miss United Kingdom, 17-year-old Kirsty Roper, was third runner-up. The new Miss World, who also holds the Miss Iceland title, is a bodybuilder who swims and plays the organ. She said traveling is her life's ambition. The title involves world travel, modeling and sponsorship.
