The tiniest Windsor is being christened on Monday, July 9-and to celebrate the occasion, Prince Harry, his uncle, reportedly dropped £8,000 (that's around $10,620) on a first-edition Winnie-the-Pooh book.
Kate's sister, Pippa Middleton, was also in attendance, and looked lovely in an icy pale blue.
There they would be joined by the Duke and Duchess of Cornwall and the Duke and Duchess of Sussex along with other guests.

They were served slices of cake taken from a tier of William and Catherine's wedding cake, the Palace said.
Prince Louis' christening marked the first time the family of five appeared in public together.
Prince Louis' final godfather is Guy Pelley, who runs Tonteria, a London nightclub that used to be one of Prince Harry's favorite places to party. He has been banned from driving three times, including twice for drink-driving and once for speeding. And perhaps most importantly, Van Custem's daughter Grace was a bridesmaid at William and Kate's 2011 wedding, where she was famously photographed holding her ears pouting atop the Buckingham Palace balcony.
Still intact after eating the seven-year-old cake, Kate was out today attending a service at Westminster Abbey to commemorate 100 years of the RAF. She is the wife of Robert Carter, who belongs to a family of wealthy landowners.
