The Princess of Wales shares an incredibly close bond with her family and after Pippa Middleton, acted as her maid of honour at her 2011 royal wedding, Kate supported her younger sister at her nuptials.
Pippa married hedge fund manager James Matthews in a countryside wedding on 20 May 2017 at St Mark's Church at Englefield Estate, Berkshire, close to the Middleton's family home, Bucklebury Manor.
While she was said not to have an official role as maid of honour, the then Duchess of Cambridge was on hand to lead the page boys and flower girls into the church, and assisted the bride as she prepared to walk down the aisle.
HELLO! takes a look at Kate's best supportive sister moments from the day as Pippa and James celebrate their seventh wedding anniversary.
Since their wedding, Pippa and James have become parents to three children – Arthur born in 2018 and daughters, Grace and Rose, born in 2021 and 2022 respectively.
James's father is Laird of Glen Affric, a 10,000 acre estate in Scotland, which he will one day inherit, and in 2021, he purchased 72-acre Bucklebury Farm Park for £1.5 million, close to their Berkshire mansion.
