Royal Wedding 2018: Princess Charlotte masters the royal wave

She may be only 3 years old, but the royal toddler has those etiquette rules down pat.

The adorable toddler served as one of the ten bridesmaids and pageboys at Saturday's royal wedding, where her uncle Prince Harry married Meghan Markle in a much-anticipated publicized event. Prince George, 4, was also a pageboy, and the two joined the others in the procession behind Meghan Markle at St. George's Chapel.

Following the ceremony, Charlotte and George joined mom Duchess Kate dad Prince William, Prince Charles and Meghan's mom Doria Ragland on the steps of the chapel to wave goodbye to the newlyweds. While George remained reserved behind the Duke of Cambridge's leg, Charlotte held Kate's hand and offered the most energetic wave.

A similar situation occurred following the birth of Prince Louis nearly a month ago -- George remained ever so stoic, while Charlotte delighted crowds outside the Lindo Wing with her royal wave.
