Prince William, arguably the most popular living royal, will have to wait another two years before becoming a tourist attraction. According to Britain's Daily Express, Madame Tussaud's famed wax museum has reversed its plan to ask the heir to the throne to pose for a wax figure, something it had planned to do on his recent 18th birthday. Instead, the powers that be (or, beeswax, actually) hope to ask Wills to sit when he's 20. Why? Because even though at 6-ft.-plus he already towers over his father, Prince Charles, Prince William probably hasn't stopped growing. "We don't want to have to continually change (his image)," said a Tussaud's spokesperson. "It's a time-consuming and expensive process, so we'd rather wait until he gets a bit older."
