While huge crowds and loud planes may be thought to be the main attraction, Charlotte sticking out her tongue while George, 4, looks out in awe was just as exciting. Three-year-old Charlotte -- who's made headlines for her iconic wave before -- was also spotted dancing with her arms in the air.
Prior to the cute display, the fab four -- William, Kate, Meghan and Harry -- attended a service at Westminster Abbey in London, England, Tuesday morning.
The group was together on Monday too, for Prince Louis' christening. The 2-month-old brother of George and Charlotte was surrounded by his grandparents, aunts and uncles for his big day, though Queen Elizabeth was notably absent.
