Princess Eugenie and Jack Brooksbank's Royal Wedding Day: See All the Photos

Princess Eugenie and Jack Brooksbank's wedding day is here!

The youngest daughter of Prince Andrew and Sarah Ferguson will tie the knot with the Casamigos ambassador today at St. George's Chapel at Windsor Castle. As we count down the minutes until the ceremony, guests are starting to arrive at the wedding venue. The venue is the same location where Eugenie's cousin, Prince Harry, married Meghan Markle just months ago on May 19. The Duke and Duchess of Sussex will be in attendance at the ceremony, along with Prince William and Kate Middleton.

The Duke and Duchess of Cambridge's eldest children, Prince George and Princess Charlotte, will be a part of the couple's royal wedding party, with George serving as a page boy and Charlotte as a bridesmaid.

Eugenie, 28, and Jack, 32, announced their engagement in Jan. 2018 after eight years together. The duo were introduced by mutual friends during a skiing trip to Switzerland in 2010. Jack proposed to Eugenie while on vacation in Nicaragua in early 2018 with a pale pink padparadscha sapphire and diamond ring.
