The pair later treated their two sons, 3-year-old Kingston and 15-month-old Zuma to a boat ride.
The Stefani/Rossdale clan flew to the Caribbean last week after spending Christmas in the UK.
They joined celebrities such as Lindsay Lohan, Beyonce and her husband Jay Z, Orlando Bloom and girlfriend Miranda Kerr, Jason Statham and his girlfriend Alex Zosman, as well as Chelsea boss Roman Abramovich and his girlfriend Dasha Zhukova who have also been spotted in St Barts over the New Year period.

Last year the family were in LA for the festive season, but Rossdale revealed: 'We alternate each year. Last year we stayed in the Los Angeles area, but now we're excited about having an old-fashioned, European holiday.'
The family's London home was burgled in September.
Thieves smashed the front door down and the flat they let to Dame Elizabeth Forgan, head of the Arts Council, was broken into.
However the burglars were unable to break into the flat shared by Stefani and her family.
