THIS couple will never forget their daughter's birthday - she shares it with Her Royal Highness Princess Charlotte of Cambridge.

Sophie and Simon Walker-Porter welcomed their own little princess Bella Faith into the world on Saturday.

Sophie, 27, was 11 days overdue and reckons her daughter was stubbornly hanging on until the royal baby arrived.

Bella was born by water birth at Barnsley Hospital, weighing 7lbs 6oz.

Sophie and Simon, 29, a senior personal banker at HSBC, of Blenheim Road, plan to register their daughter for a special silver penny issued by The Royal Mint for all sharing the new princess's birthday.
