The palace is upset that photos of the Duke and Duchess of Cambridge enjoying a private vacation were published, stating that it is a "clear breach of the couple's right to privacy."
Less than six months ago, the same privacy issue came up when Chi and it's French publication, Closer magazine published topless photos of Kate Middleton, causing an uproar in the palace.
The latest pictures published are of Kate and William walking on a beach on an island in the Caribbean, enjoying what they thought was some private time away.
The photos on Chi include Kate in a blue bikini that reveals a small baby bump with the headline that reads, "The belly grows."
A second photo is of William with his arm around Kate walking on the beach, a place they thought was private and without paparazzi.
The palace issued the following statement about Kate's baby bump photos:
"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."
Last week, paparazzi took photos of pregnant Kate Middleton while she was out shopping, with many Royal baby-bump watchers excited to see the Duchess of Cambridge looking happy and healthy.
The photos were in good taste and weren't taken while Middleton was on vacation with her husband, but instead while she was out and about.
To snap a random photo while the Duchess is out shopping is one thing, but obsessively tracking her down on a private vacation seems like stalking.
The couple's baby is due in July and surely there will be plenty of photos of the new baby released by the palace.
For now, it might be a good idea for the paparazzi to leave Kate and her baby bump alone so she can relax and enjoy her pregnancy.
