Today the Duchess of Cambridge will play godmother as she takes on the task of christening the new Princess Cruises 3,600-passenger ship, the Royal Princess, in Southamption.

Pregnant Kate Middleton will officially name the vessel by breaking a bottle over the hull. She'll then head on board for a brief cruise and visit the ship's bridge. The Duchess is sure to be impressed by the liner, which boasts the largest outdoor cinema and  pastry shop at sea, as well as two outdoor pools and balconies on all outside staterooms.
