Sky News presenter Kay Burley has told the Duchess of Cambridge to buy a six-pack of big pants, after a photograph of the Duchess's bottom was printed in German daily newspaper Bild.
Ms Burley seemed unable to keep a straight face while discussing the "bottom-gate" row on Sky News Tuesday.
Discussing the controversy on Sky News with the channel's royal correspondent Paul Harrison, Burley chortled: "That's a very serious face that you've got talking about this story, isn't it?"
She later added: "Get yourself a six-pack of big pants, Kate. I mean, seriously."
While UK newspapers opted not to print the photo of Kate's bottom, the German newspaper has since followed up Monday's editorial with a cheeky piece entitled: “Look, dear Brits… These 10 bums are our Royal moments,” alongside a selection of 10 pert German backsides.
The initial publication of the picture of Kate's behind prompted an international outcry and has rekindled the debate about how to protect the privacy of the Royal couple.
The Duke and Duchess of Cambridge have been dragged into a series of privacy rows with the foreign press in recent years after photographs were published of Kate in a bikini while she was pregnant, and topless while on honeymoon.
In February last year, Italian and Australian magazines published photographs of Kate with her bump on display while she walked along a beach on the secluded Caribbean island of Mustique.

In 2012, the Prince and Duchess launched a legal case against French magazine Closer that published topless shots of the Duchess taken while she was on holiday in Provence Chateaux. Clarence House releases a statement comparing that publication with the “worst excesses of the paparazzi during Diana’s life.”
The magazine’s editor was unrepentant, saying the resort’s pool was in full view of a public road and easily seen by the public. However, Chateau d’Autet has a secluded woodland setting, and is hundreds of metres from the closest public road – so the royals were in '‘full view'' only as long as they were being viewed through a large telephoto lens.
