UK tourists will have to wait for waxed royal Kate Middleton

She may marry into Britain's royal family in April, but prince William's fiancee Kate Middleton will not take her place alongside the royals at Madame Tussauds until later in 2011.

The London wax sculpture museum said it will try to book a sitting with Middleton after her wedding on April 29 and it would then take sculptors up to four months to make the model, the BBC reported on its website.

The museum was also waiting to hear if Middleton would donate an outfit for the waxwork.

Britain's queen Elizabeth, her husband Prince Phillip and heir-to-the-throne prince Charles as well as his wife Camilla and his sons William and Harry are already cast in wax at the popular stop on London's tourist trail.

"It looks likely it will be shortly after the wedding and then it takes four months to complete," a spokesperson for Madame Tussauds said. "I imagine the sculptors will probably go to her and the sitting normally takes a couple of hours."

Middleton's waxwork look will depend on what she wants and whether she can donate clothing.
