Kate Middleton christened the new ‘Royal Princess’ cruise ship in a ceremony in Southampton. The Duchess officially named the ship as she stood on the naming platform with the ship's Captain Tony Draper. I name this ship Royal Princess. May God bless her and all who sail in her, Middleton said. She then cut the rob that sent a bottle of Moet & Chandon champagne crashing into the ship, officially welcoming the new ship into the fleet of Princess Cruises.
