Kate Middleton and Prince William married in April 2011

Kate Middleton and Prince William are said to be 'surprised and upset' after an Australian magazine printed pictures of them on their honeymoon in the Seychelles.

A snap of the couple walking along the beach hand in hand wearing only their swimwear was put on the cover of Woman's Day.

Another 15 photos, including shots of Kate and William, both 30, swimming in the Indian Ocean, were printed inside the mag.

'The Duke and Duchess Of Cambridge considered their honeymoon to be a very private event after their hugely public wedding,' says a St James's Palace spokesman.

'For this reason they asked the media to respect their privacy. That is something they continue to do.'
