It’s officially been one year since Princess Beatrice and Edoardo Mapelli Mozzi said "I do."

To commemorate the special occasion, Mozzi took to Instagram on Saturday and shared a candid selfie of the two.

"I can’t believe it has been 1 year," wrote the 38-year-old. "Every second of every day has been so full of joy, happiness, laughter and love. You are the kindest, loveliest and most beautiful person in the world. Thank you my darling for every second."

This year is particularly an exciting one for the couple. In May, Buckingham Palace announced that Beatrice, 32, is expecting a baby.

The palace said that the granddaughter of Queen Elizabeth II and her husband are due to have their first child in autumn.

"Both families are delighted with the news," said a palace spokesperson.

Beatrice, the elder daughter of Prince Andrew and ex-wife Sarah Ferguson, married the property developer in July 2020 at a small ceremony constrained by coronavirus restrictions.

Beatrice’s younger sister Princess Eugenie and her husband Jack Brooksbank welcomed their first child, a son named August, in February.
