Prince George and Princess Charlotte made their third march down the aisle in the last few years on Saturday (Sept. 22) for Kate's dear friend Sophie Carter, who tied the knot with Robert Snuggs at St Andrew's Episcopal Church in Norfolk, where the Cambridges have their country home. Prince William and Kate's eldest son was pageboy while their daughter took another turn as bridemaid, clad in a pretty floral crown like her mom. The Middleton family was also on hand for the festivities, including Carole, Michael and James, though pregnant Pippa sat this one out. While Prince George stole the show with his hilarious marching antics and funny faces, Charlotte seemed sweetly calm in the arms of her mom and the bride.

At one point Prince George started marching, much to the amusement of their mom Kate, who is still finishing up her maternity leave after giving birth to Prince Louis. It's believed that the third Cambridge kid was at home with his nanny Maria Teresa Turrion Borrallo.

The Duchess of Cambridge opted for a gorgeous cornflower blue coat dress by Catherine Walker, which she paired with a stunning oversized floral headband. The rose-adorned topper by Juliette Botterill Millinery, which retails for $730, called the mind the floral headpiece she wore to Prince Louis' christening earlier this year.

Sophie, who looked stunning in a classic white headband, lace-edged veil and white gown with a scalloped lace jacket, is one of Princess Charlotte's godmothers. William and Kate's middle child was clearly comfortable in her arms as her brother smiled sweetly for the camera.
