As godmother, Perry will not only fulfil the maritime tradition of blessing and officially naming the vessel, but she will perform during the christening ceremony in August before the vessel embarks on its inaugural voyage from Reykjavik.
 

Harry Sommer, president and chief executive of NCL, said the brand was "excited" to welcome the "one-of-a-kind artist" as godmother of Prima.

"We are so incredibly proud that she will be part of the Norwegian Cruise Line family and look forward to launching our beautiful, innovative ship with her in August," he added.

Perry said her favourite form of holiday with her family was on the water. "Every morning that you wake up, you get to experience an incredible new view," she added.

"I love that I get to christen her with my good vibrations, and I’m so excited for this new, beautiful, high-end, high-tech ship to take the seas, and provide once-in-a-lifetime vacations for so many families."

Prima will offer inaugural voyages to Northern Europe from Southampton, Amsterdam and Reykjavik from 12 August, sailings to Bermuda from New York from 6 October and Caribbean itineraries from Texas and Miami beginning 27 October.
