Adorable Prince George, Princess Charlotte take part in Pippa Middleton's wedding

George, 3, served as a page boy while Charlotte, 2, served as a bridesmaid.

George, who turns 4 in July, served as a pageboy at Middleton's wedding to financier James Matthews, while Charlotte, 2, served as a bridesmaid.

George and Charlotte joined the other page boys and bridesmaids in wearing custom-made outfits designed by Pepa & Co. Charlotte and her three fellow bridesmaids wore dresses accented by a sash and flower crowns atop their heads.

George and his three fellow page boys wore gold, knee-length trousers and collared shirts.

George and Charlotte’s nanny, Maria Turrion Borrallo, was also photographed at the church with the children.

Middleton, 33, and Matthews, 41, tied the knot at St. Mark’s, located just six miles from Bucklebury, where Middleton was raised. Middleton donned a white gown designed by Giles Deacon and a bespoke veil designed by milliner Stephen Jones that featured tulle and embroidered pearls.

While the American wedding tradition is to include bridesmaids closer in age to the bride, the British tradition varies.

Kate's four young bridesmaids each wore ballerina-length dresses using the same fabric as Kate's wedding gown, adorned with a pale gold sash made of wild silk.

The two page boys, Billy Lowther-Pinkerton and Tim Pettifer, wore child-size uniforms in the style of Foot Guards officers worn at the time of the Regency in the 1820s.
