Sources say the Hollywood couple has snapped up a private mansion in a new development in posh Turks & Caicos.

The ultra-exclusive island can only be reached by boat and features homes ranging in price from $3 million to $8 million as well as a five-star hotel.

According to US reports, Zeta-Jones, 37, and Douglas, 62, have bought a five-bedroom residence at Dellis Cay. Last month they attended a dinner in Miami held by the property's developer, Dr Cem Kinay, joined by investor Martha Stewart.

Douglas already owns a home in Bermuda with his Oscar-winning actress wife. They also have homes in Los Angeles, New York, and Majorca, as well as the Colorado ski resort of Aspen. A spokesperson for Douglas did not return calls.

Earlier this month the childhood home of Chicago star Zeta-Jones in Swansea, Wales, went on the market with a price tag of £425,000.
