Princess Eugenie has shared an adorable post to mark her first wedding anniversary to Jack Brooksbank.

The couple wed at St. George's Chapel at Windsor Castle in October last year, just five months after Meghan Markle and Prince Harry said 'I do' in the same place. And to mark their one-year wedding anniversary, Eugenie took to Instagram to share an intimate, behind-the-scenes video showing the lead up to the big day - as well as some wonderful moments form the ceremony itself, including when they exchanged vows. "This was the greatest day of my life...forever and always," she captioned the post. "Happy one year anniversary, my Jack." Buckingham Palace also shared a tribute to Princess Eugenie and Mr. Brooksbank on Saturday, alongside a photo of the two of them kissing outside the chapel after the ceremony. "Congratulations to Her Royal Highness Princess Eugenie and Mr Jack Brooksbank on their 1st Wedding Anniversary," they said. "Today marks one year since Her Royal Highness and Mr Brooksbank exchanged vows as St George’s Chapel within the grounds of Windsor Castle on October 12th, 2018." It's not the first time that Princess Eugenie has given fans not the royal family a behind-the-scenes glimpse of her wedding day. For Valentine's Day, she posted a photo of the two of them sharing a kiss in the Scottish Stage Coach they took after exchanging vows. "Happy Valentine's Day..." she captioned the post, alongside a string of heart emojis. A huge congrats to the couple.
