Princess Charlotte, four, follows in the footsteps of her six-year-old big brother George today, joining him at Thomas’s Battersea school in southwest London.

She was dropped off for her first day of school on Thursday by her parents Kate Middleton and Prince William, along with Prince George. Adorable in matching navy blue school uniforms with red trim, the royal sibs waved and smiled confidently for the camera, and Charlotte, with typical spirit, gave her ponytail a sweet little flip.

According to a story in People, Princess Charlotte will forego her royal title and instead be known to the other children as simply Charlotte Cambridge, or go by her nickname “Lottie.” Her brother, the future King, is similarly known as George Cambridge.

The great-granddaughter of Queen Elizabeth, Charlotte is fourth in line to the throne, following — in ascending order — Prince George, her father William and her grandfather Prince Charles. Younger brother, Louis, who celebrated his first birthday in April, is fifth in line to the throne.

Thomas’s Battersea school has an enrollment of  560 boys and girls between ages four and 13, with annual fees for each four-year-old of around $24,000 US. Charlotte’s tuition, however, will be reportedly discounted since her brother is already a student at the school.
