London, Feb. 13 (ANI): St James' Palace said that the photographs, taken on the exclusive Caribbean island of Mustique, where Kate is holidaying with her husband Prince William and close family, were a "clear breach" of their privacy.
A spokesman said that the Royal family is disappointed that images of the Duke and Duchess on a private holiday look likely to be published overseas, the Telegraph reported.
The pictures, due to hit the newsstands on Wednesday in the Chi magazine, show the 31-year-old Royal striding through knee-deep turquoise water and strolling on the beach with William.

In the photograph, she is seen smiling happily and her pregnant belly is said to be clearly visible.
"Kate and William in Mustique - the belly grows" was the headline on the front page of the glossy magazine.
The magazine called the Royal couple's holiday "a honeymoon for three."
The couple are on a private holiday on the exclusive island which prides itself on offering prominent people the perfect retreat. The images are believed to have been taken last week. (ANI)
