An Italian magazine that published topless photos of Prince William's wife last year is reportedly printing new pictures of the pregnant duchess on a beach holiday in the Caribbean, provoking condemnation from royal officials.

St. James's Palace expressed disappointment Tuesday that the pictures may be published, saying it would amount to a "clear breach of the couple's right to privacy." It did not say whether officials would be prepared to take legal action against the gossip magazine.

The magazine, Chi, is said to be planning to publish the pictures Wednesday. The photos reportedly show the Duchess of Cambridge - the former Kate Middleton - wearing a bikini and strolling on a beach with William on the island of Mustique.

Last September, the magazine - owned by former Italian Premier Silvio Berlusconi - published a 26-page special featuring topless photos of the duchess while she and William vacationed in the south of France.

The royal couple took legal action to halt the use of those intimate photos, but had only limited success. Although a French court ordered gossip magazine Closer to stop further publication of the pictures, they went on to be published in Chi, other publications across Europe, and on the Internet.
