Fans spot picture of Prince William and Kate Middleton in royal office

When Crown Prince Haakon and Crown Princess Mette-Marit of Norway shared a look inside their royal residence on Thursday, eagle-eyed fans spotted their home office has a portrait of another royal couple on display. Some were surprised to see that a framed photo of the Duke and Duchess of Cambridge sits on top of a piano in the back of the room alongside a selection of other photos and books.

The portrait was likely a gift presented to Haakon and Mette-Marit the last time they hosted Prince William and Kate on a royal tour. The Cambridges visited Norway in February 2018 when Kate was heavily pregnant with their youngest son Prince Louis, and attended a number of engagements with their Norwegian counterparts. They also gave the King and Queen of Norway a copy of the portrait during their visit.

A series of photos shared on the Norwegian royal family's official Instagram account on Thursday showed the Crown Prince and Princess sat side-by-side while conducting a video conference at their home due to the coronavirus pandemic, with a stack of books used to prop their laptop up on their wooden desk.

The room has a chic blue colour scheme, with wooden panelling on the lower half of the walls, and artwork and a gold-framed mirror adding the decorative touches. Meanwhile, a dusky blue sofa and chaise longue that tie in with the muted colour scheme can be seen in the background, so the couple could relax when they finish work.
