Princess Isabella turns 18 on 21 April and in honour of her upcoming milestone the Danish royal family shared a slew of never-before-seen photos of the Princess.
As well as adorable baby photos Isabella, Queen Mary also makes an appearance most notably in a series of special black and white snaps which show her giving her daughter a piggy-back.
Other sweet moments show the mother-daughter duo posing for a close-up selfie as well as being dressed up to the nines behind the scenes at their royal home.
Alongside the photos were the words: "Small glimpses from childhood to 18 years. In honour of Her Royal Highness Princess Isabella's 18th birthday on Monday, Their Majesties The King and Queen are sharing a selection of memories from the family's digital photo album."
Other moments featured in the collage showed Isabella with her siblings, Prince Chrisitan, Prince Vincent and Princess Josephine, as well as her father King Frederick.
Fans had questions
It's safe to say the photos delighted Princess Isabella's fans who took to the comments section with sweet messages for the royal.
"What a nice Collage to celebrate the Princess," one penned. Meanwhile, a second added: "Happy birthday, Your Royal Highness!"
However a third couldn't help but notice King Frederick's tattoos in one photo of him and Isabella enjoying a swim and asked: "The King's got a tattoo?" to which another replied: "Yes he has a couple."
Unlike with the British monarchy where tattoos are not usually permitted, it is more common for royals from other countries to have tattoos. King Frederick's father King Frederick IX reportedly had nine of his own!
