Yui Mok/PA WirePrincess Eugenie and Jack Brooksbank's wedding day is finally here!
The two tied the knot at St. George's Chapel at Windsor Castle on Friday. While the attention was certainly centered on the bride and groom, Prince George and Princess Charlotte had a few show-stopping moments, too.
The 5-year-old prince served as page boy while his 3-year-old sister served as a bridesmaid. Luckily, they had a bit of practice before the big day. After all, they performed the same roles at Prince Harry and Meghan Markle's wedding in May and at Pippa Middleton and James Matthews' wedding the year before.
Their little brother Prince Louis, however, was not in attendance. The young royal was most likely too little to attend. He is, after all, only five months old.

The little lady clearly isn't camera shy.
Whoops! Charlotte takes a little fall on the chapel's steps.
The adorable duo wear ensembles designed by Amaia Arrieta of Amaia Kids. Per the Palace, the design incorporates the Mark Bradford artwork included in the Order of Service.
George and his cousin Savannah Phillips have a little too much fun during the ceremony.
It certainly is a blustery day for a wedding.
Something has clearly caught the 5-year-old royal's attention.
Charlotte is one of six bridesmaids and George is one of two page boys.

She totally nails it!

Charlotte's bridesmaid's bouquet consists of posies of Lily of the Valley and spray roses and serves as a miniature version of Eugenie's bouquet.
Something was clearly too much for the little princess to handle.
George isn't exactly displaying royal behavior.
The wedding took place nearly nine months after the couple announced their engagement. After the beautiful ceremony, the two embarked on a carriage procession and enjoyed a reception hosted by Queen Elizabeth.
Congratulations to the happy couple!
