Prince Harry and Meghan Markle tied the knot in a beautiful ceremony at St. George's Chapel on May 19, and Prince George and Princess Charlotte looked too cute for words. Sadly, Prince Louis was left at home, but his brother and sister played a big part in their uncle's wedding, serving as pageboy and bridesmaid. For the special occasion, George looked adorable in a black suit, and Charlotte was precious in a white dress.
Of course, this wasn't George and Charlotte's first big wedding. Back in May 2017, they were both part of the bridal party for their aunt Pippa Middleton's nuptials, during which they also served as pageboy and flower girl. Read on to see more adorable photos of the young royals helping Harry and Meghan on their big day, but be warned: they'll make you melt.
