It was a big day for Danish royals Prince Vincent and Princess Josephine on Saturday, as the 15-year-old twins celebrated their confirmation at Fredensborg Palace in Denmark.

And in a post shared on the Danish royal family's official Instagram account, the royals offered fans a glimpse into the special day – including a sweet blink-and-you'll-miss-it sibling moment from Vincent and Josephine that many brothers and sisters will find relatable.

Lady Susan Hussey made a rare appearance on Tuesday when she joined members of the royal family at a reception at Buckingham Palace in honour of the late Queen's centenary.

There are several home comforts Andrew Mountbatten-Windsor was forced to leave behind when he was ousted from Royal Lodge in Windsor earlier this year.

After King Charles initiated a formal process to remove the Style, Titles and Honours held by Andrew amid his links to paedophile financier Jeffrey Epstein, he relocated from his long-term family home, Royal Lodge on the Windsor Great Park estate, to the Sandringham estate, where he now lives at a converted farmhouse called Marsh Farm.

While renovated, the new property is decidedly more modest, without 30 rooms and 98 acres of land, which housed a swimming pool, six lodge cottages, a gardener's cottage and a life-size playhouse that was gifted to his late mother Queen Elizabeth. However, there's another lesser-known feature that King Charles' disgraced brother was never pictured enjoying – the aviary.

That is a wrap on this busy day honoring what would have been the late Queen's 100th birthday.

We'll be back tomorrow with our regular (royal) programing. 

Until then!
