Scherzinger will also create “spectacular music and dance extravaganzas” for the line as part of an exclusive entertainment partnership.

Arvia, a sister vessel to P&O’s Iona, will be christened on 16 March in Barbados with the beachside ceremony broadcast live on YouTube at 7pm.

P&O Cruises president Paul Ludlow said: “As a global superstar Nicole is well placed to create contemporary and breath-taking late-night shows which will be performed in SkyDome on our two newest ships Iona and Arvia.

“Through her many appearances on some of the UK’s best loved shows Nicole has won the hearts of the British public. She really is the epitome of zest for life and as a critically-acclaimed talent she joins a line-up of world-famous godmothers and partners for P&O Cruises. Her involvement reflects everything which P&O Cruises stands for – a modern, forward-thinking holiday company which has always excelled in the levels of cutting-edge entertainment we provide.”

Ludlow said the lines was “always striving to set new standards” for the shows onboard it fleet and the new partnership with Scherzinger “takes that to another level”.

Scherzinger added: “This is an extraordinary and special opportunity for me to create a visual and musical feast for people to immerse themselves in, with the sea as their backdrop, giving them something to truly remember. I want to create an experience to remember for the audiences of Iona and Arvia and I am delighted to become part of the P&O Cruises family.

“I have always felt as though I am honorary Brit and to be asked to name Arvia in Barbados really is the icing on the cake and I cannot wait to perform my godmother duties in the most beautiful of Caribbean locations.”
