Princess Charlotte has that royal wave down.
The 3-year-old royal stole fans' hearts when she gave another adorable wave ahead of Prince Harry and Meghan Markle's wedding on Saturday.
Upon arriving at St. George's Chapel in Windsor with her fellow bridesmaids and mother Kate Middleton, the little princess waved from the car. After stepping out of the vehicle, she then turned to the crowd and greeted everyone with a royal wave. She also gave another wave after Meghan and Harry tied the knot and rode off for their carriage procession.
Another particularly silly moment was when Charlotte stuck out her tongue.
The niece of the groom was one of six bridesmaids. There was also Florence van Cutsem, whose cousin Grace van Cutsem was a memorable bridesmaid in Kate and Prince William's wedding, as well as Ivy Mulroney, the daughter of Meghan's friend Jessica Mulroney. The other bridesmaids included Harry's goddaughter, Zalie Warren, and Meghan's two goddaughters, Remi Litt and Rylan Litt. Like Charlotte, they all arrived with their mothers.
There were also four page boys, including Charlotte's brother Prince George, and her father William was best man.
This wasn't the first time Charlotte has greeted fans with a royal wave. She also gave one upon entering the hospital after her brother Prince Louis was born. Although, the baby is too young to attend today's ceremony.
This also wasn't Charlotte's first time serving as bridesmaid. She performed the duty last year for her aunt Pippa Middleton's wedding.
The ceremony began at 12:00 p.m. After Meghan and Harry said "I do," they embarked on a carriage procession.
Then, they celebrated their newlywed status with a reception for all 600 guests, as well as a private reception for 200.
