The Willoughby sisters consist of ITV's Holly Willoughby and her fictional sisters, Hillary, Tiffany and Whitleigh. The four blonde bombshells are sweet, gorgeous, curvaceous and voluptuous women from the United Kingdom of Great Britain, who love to flaunt their figures when turning up the heat on a tropical island at a sunny beach, or fighting along with the Kardashian Federation in the battle against monsters and criminals. #ITV #HollyWilloughby #BlondeBombshells #Curvaceous #Voluptuous
