But you'd better be quick. Only the first 100 Charlottes to turn up at The Strand in London, Kirkstall Road in Leeds, Liverpool ONE, Hanover Street in Edinburgh and The Trafford Centre in Manchester will get a free main meal. And they have to have ID to prove they share a name with the Duke and Duchess of Cambridge's newborn daughter.
"The royal birth is such a momentous occasion, we want to celebrate and welcome the new arrival in a way that our customers can also enjoy," said Kathryn Austin, Pizza Hut's director of HR and marketing. "A new royal baby and a free pizza, sounds like the perfect combination."
Princess Charlotte Elizabeth Diana was born on Saturday, May 2 at 8:34 a.m., weighing 8lbs 3oz.
