Another added: “Was this photoshopped? I mean it looks like they were photographed separately then put together?

“Mary looks exquisite and Frederik, well the King looks like he just rolled out of bed.”

While a third posted: “Terrible translation. So stiff and awkward. AI.”

Others pointed out the placement of Queen Mary’s hand in front of King Frederik’s, claiming it looked out of place.

Another post read: “It looks like Queen Mary has been put into the photo of Fred. The hand position is identical.”

But the Danish Palace has confirmed the picture is real and said: “The Royal House’s official gala portrait has not been manipulated.”

The picture featured the Australian-born Queen standing alongside the King wearing a deep green velvet and lace gown designed by Birgit Hallstein, along with the Danish Emerald Parure.

It comes after as many as 16 “errors” were found in the Mother’s Day portrait of Kate, resulting in several picture agencies recalling the image.

Following the controversy, Kate took to social media to take responsibility for the editing and to issue an apology.

She wrote: “Like many amateur photographers, I do occasionally experiment with editing.

“I wanted to express my apologies for any confusion the family photograph we shared yesterday caused.

“I hope everyone celebrating had a very happy Mother’s Day. C.”
