Queen Elizabeth accidentally showed never-before-seen picture of Harry and Meghan

During an official meeting at her residence, photographers captured a photo fo the monarch that also showed a never-before-seen photo of her grandson and his new wife.

The official Instagram handle of Buckingham Palace posted a photo of Queen Elizabeth II shaking hands with the Australian High Commissioner to the United Kingdom, George Brandis, at the end of May.

In the background of the photo, social media users spotted a framed photograph of the Duke and the Duchess of Sussex sitting on the side table beside the fireplace of the Queen's residence.

In the photograph, Meghan's hand is rested on Harry's chest as the couple posed in matching blue outfits. Meghan wore a light blue dress while Harry had donned a navy blue suit

It appears possible that it was the same suit that Prince Harry wore during his and Meghan's engagement photos that were taken at the end of 2017.

It wasn't entirely clear when the photo was taken but it was likely to be captured before the couple's big wedding in St George's Chapel, Windsor Castle, on May 19, and possibly as part of their engagement photos.

According to Metro UK, it is the first time the photo has been spotted, as previous images of the Monarch welcoming guests in her sitting room show a different photo in the background.

Following their lavish ceremony, the couple have appeared at celebrations for Prince Charles' 70th birthday, at a cousin of Harry's wedding, and at Royal Ascot. Meghan has also embarked on her first solo duty with Queen Elizabeth.

The couple put off their honeymoon plans in order to attend Prince Charles' birthday party, but jetted away shortly after the garden party. The royals have chosen to keep their honeymoon destined under wraps, even after returning home.

Among the rumored destinations for their romantic getaway were Canada, Rwanda, Barbados, Hawaii, and Botswana.

Kensington Palace clarified in an official statement before the couple's departure that although the wedding was a public affair, the honeymoon will be treated as a private matter.

As reported by CNN, the Duchess of Sussex has been named one of the top 25 influential women working in Britain. Meghan made her way into Vogue's inaugural Vogue 25 list alongside Amal Clooney and J. K. Rowling.
