Kate is the eldest of three – Pippa, 37, being the middle child and their brother James, 33, being the youngest.
Pippa was famously Kate’s maid of honour at her 2011 wedding to Prince William, where she first garnered intense media attention.
The Middleton sisters live close to each other too, with the Duke and Duchess of Sussex at Kensington Palace and Pippa and James in Chelsea, London.
Their mother, Carole Middleton, lives just outside of London in Berkshire, so is not far away from her young grandchildren.
