WELL, watcha think about that? Chart star A-lister Nicole Scherzinger treated passengers to a special stripped back show as she officially named new cruise ship Arvia tonight.

Backed by just a guitarist and two singers, the 44-year-old Pussycat Dolls founder belted out a sultry cover version of Screamin’ Jay Hawkins rhythm and blues classic I Put A Spell On You.

The she took the Dolls’ dynamic Don’ Cha right down to its bare bones before building it back up again in an exclusive set chosen for the Caribbean party ceremony.

Arvia, P&O Cruises’ newest ship, was moored off Heywood Beach on the sunshine isle of Barbados for the show, which was also broadcast live on Youtube.

Before the show, Nicole had posed up a storm with Captain Robert Camby on Arvia’s bridge, and inspected the ship’s senior officers before triggering the traditional bottle smash ceremony.

A 15-litre demijohn of Mount Gay Black Barrel rum sped down a wire from the top of the ship to smash against the prow, blessing Arvia with fair winds and good fortune ahead.

Earlier, hitmaker Olly Murs entertained guests on the beach with another semi-acoustic set after being introduced by DJ Sara Cox, watched by the Prime Ministers of Barbados and Trinidad.

As part of a wider collaboration and exclusive entertainment partnership, Nicole Scherzinger will create new music and dance spectaculars for P&O Cruises’ ships Arvia and Iona.

Even Gary Barlow, Music Director of the 710 Club on Arvia and Iona got in on the act, sending a message wishing the ship well.
