She jetted in to the island by helicopter before performing at Roman Abramovich’s glitzy £5million New Year’s Eve party, and seems in no hurry to return to America just yet.
Fergie was making the most of her time in St Barts yesterday, living it up aboard Sean 'P Diddy’ Combs' monster yacht.
And always quick to show off her humps, Fergie struggled to contain her curves in a gold bikini.
Boom boom pow: Black Eyed Peas singer Fergie donned a shiny gold bikini for a day on P Diddy's boat
The 35-year-old Black Eyed Peas singer, who is often seen exercising outdoors, showed off a toned body as she lapped up the luxury on the yacht.
The curvy singer was wearing a gold halter neck bikini which sported considerable cleavage as she sunned herself aboard the boat.
As Fergie, real name Stacy Ferguson, enjoyed the opulent surroundings with the boat’s guests, her husband Josh Duhamel spent the day on the shore at the beach.

Fergie topped up her tan and chatted to Kim Porter, the mother of P Diddy's twin girls, who has been spending time with the rapper.
But despite the luxurious surroundings Fergie seemed to be eagerly awaiting her husband's return as she peered out to sea from the boat.
As Josh's tender made its way back to the boat, Fergie spotted her man and began frantically waving her arms at him.

With a huge grin on her face she greeted her man, who had only been gone a few hours, with a great big bear hug.
Later that day, Fergie threw on a sheer black kaftan over her bikini to head out for dinner.
The couple dined at the Ti St Barts restaurant on the island and Fergie’s translucent dress was topped off with a pair of nude high heels.
The singer opted for minimal make-up and sported a relaxed wind-blown hairstyle.
The couple jetted into St Barts on Friday and Fergie joined her Black Eyed Peas band members on stage at the Russian billionaire's star-studded bash.
