Meghan Markle and Prince Harry aren't the only stars of the royal wedding.
Among their bridesmaids and page boys were Princess Charlotte and Prince George, the children of Prince William and Kate Middleton.
While they were on their best behavior throughout the service, 3-year-old Charlotte took the opportunity to stick out her tongue at the cameras waiting for them as they left St. George's Chapel.
Her 4-year-old brother was less confident, and was snapped hiding behind his dad's leg after they left the ceremony.
Their 3-week-old brother, Louis, did not join them at the wedding.
Who are the bridesmaids and page boys?
The little royals were joined by the children of other family and friends.
Meghan's 6-year-old goddaughter, Remi Litt, is a bridesmaid, as is Remi's 7-year-old sister, Rylan.
Ivy Mulroney, the 4-year-old daughter of Meghan's best pal, Jessica Mulroney, is another bridesmaid, as is Harry's 2-year-old goddaughter, Zalie Warren.
At George's side is Harry's godson Jasper Dyer, 6, and Jessica Mulroney's 7-year-old twin sons Brian and John Mulroney.
What are they wearing?
George wore a miniature version of the Blues and Royals frockcoat, which is made from blue doeskin. It draws it insignia from the Blues and Royals, an old Regiment of The Duke of Cambridge and Prince Harry.
As a special memento, George has his initials embroidered in gold on his shoulder straps, as did the other Pages. The outfit was cut and made by tailors Dege & Skinner in Savile Row, Kensington Palace said.
"The Pages are not wearing hats or white waist belts for practical reasons," the palace added.
Charlotte and the other bridesmaids wore dresses designed by Givenchy's Clare Waight Keller, the designer behind Meghan Markle's wedding dress.
The dresses are Ivory silk Radzimir, hand finished with a double silk ribbon detail tied at the back in a bow, the palace said.
The bridesmaids also wore white leather Aquazurra shoes and, as a keepsake, each pair is monogrammed with the bridesmaid's initials and the wedding date.
