Sarah, Duchess of York, shared a never-before-seen photo of Princess Eugenie, wishing her younger daughter a happy birthday.

The snap of Eugenie clad in her wedding day ensemble was taken back in fall 2018, when she married Jack Brooksbank in a lavish ceremony in front of a slew of lustrous attendees at St. George's Chapel, Windsor Castle, on October 12.

"My favourite photograph just for her mum on her wedding day .. and my little girl is 30 today," captioned the duchess. "Happy Birthday my little magic dust."

For the princess's stunning bridal look, she donned a Peter Pilotto gown, a Greville Emerald Kokoshnik Tiara, and satin Charlotte Olympia peep-toe heels. She kept her makeup fresh and flush, complete with a rosy-pink pout. For the reception, the bride followed up with a champagne-hued Zac Posen gown.

Eugenie also shared a few throwback photos of her own to celebrate her birthday while also thanking royals fans, family, and friends alike for their warm birthday wishes. The mini slideshow included photos of Eugenie as a newborn with her parents, as well as adorable snapshots of the princess as a young toddler.

"Thank you for all the wonderful birthday messages. XX 💋," wrote Eugenie.
