This adorable picture of Prince Louison a bike was released by Kensington Palace to mark his third birthday today, and was taken by his mother earlier this week on the morning of his first day of nursery school. The Duchess of Cambridge just loves dressing her royal sons in shorts, evoking memories of her husbandPrince William and brother-in-law Prince Harry when they were young. Prince Louis Arthur Charles of Cambridge was born on April 23, 2018 and is fifth in line to the throne. Last year his parents marked his second birthday by releasing a series of photographs of Louis becoming acquainted with bright rainbow paints. The pictures were taken by Kate during the initial stages of lockdown in Britain, when the family was isolating at their country manor of Anmer hall in Norfolk. The Cambridges recently returned from Norfolk to Apartment 1A at Kensington Palace in London ahead of Prince George and Princess Charlotte’s return to school after Easter vacation. According to reports, Kate was spotted taking George and Charlotte shopping on Monday, with one witness saying that the children had each been given a budget and that they could buy what they wanted with their own money. The excursion on Kings Road in London came two days after the funeral of the kids’ great-grandfather, Prince Philip, at Windsor Castle. Next up, here’s why the royal women—the Queen, Kate, and Camilla—wore colorless jewels to Prince Philip’s funeral.
