A grinning Prince William (search), cast in wax, is the latest royal exhibit at Madame Tussauds waxwork museum.

Wax modelers used photos to create the life-size model, which went on display Wednesday. The 23-year-old prince, second in line to the British throne, didn't have time to sit for the sculptors.

The model of William, dressed in a black suit, blue shirt and red tie, with hands in his pockets, joins wax figures of William's father, Prince Charles (search), and grandmother Queen Elizabeth II (search) on display at the central London museum.

Modelers spent three months making the 6-foot-3-inch wax model, after receiving permission from Buckingham Palace (search).
