Princess Kate curtsies to the queen before Easter celebration

WATCH: Prince Harry to spend the Easter holiday with girlfriend Meghan Markle and her family

Prince William and Princess Kate joined Queen Elizabeth II at Windsor Castle for Easter today.

William was seen bowing his head to the queen, while Kate gave her a deep curtsy.

It is tradition for Kate to curtsy to the queen, although it is rarely seen and only happens when she first meets the monarch on any given day, so it generally takes place behind closed doors.

William's bow, meanwhile, is another sign of respect for her majesty.
