An Italian magazine published photos of Duchess of Cambridge Kate Middleton's baby bump and infuriated the royal family in the process. 

The gossip magazine Chi is the first to print royal "baby bump" photos, taken when Middleton was sunbathing in a bikini on a private holiday in the Caribbean, according to The Guardian. The publication is the same one to publish topless pictures of the Duchess, 31, on a private holiday in France back in September of 2012.

The pictures of Middleton pregnant in a bikini were taken on the Caribbean island of Mustique, where she and her husband, Prince William, were on vacation, according to the news report. The images, according to Us Weekly, are said to show Middleton in a blue bikini walking on the beach alongside her husband. The royal family is reportedly very upset that the private photos were taken, and a royal spokesperson said Chi was "a clear breach of the couple's right to privacy."

"We are disappointed that photographs of the duke and duchess on a private holiday look likely to be published overseas. This is a clear breach of the couple's right to privacy," a spokesperson for St James's Palace added.

Other media outlets have refused to print the photos. 

The photos surfaced over the weekend. One British newspaper, The Sunday People, said in an article headlined "Fresh agony over bikini snaps" that the pictures had indeed been taken but that it had "chosen not to view the pictures, and, like the rest of the British media, will not publish them."

The Chi issue with the pictures of Middleton flaunting her baby bump in a bikini will be on newsstands Feb. 13. 

A source told Weekly that the royal couple is sad that media outlets continue to publish unauthorized photos of them. 

"It's been a real sour note for the end of their trip," the insider said. "For Catherine, it was the first time she had shown her baby bump, and so for it to be exposed so quickly has shaken her up a little. They thought with the privacy laws on the island they would be able to spend a moment outside of the house without this happening."
