Their thoughts no doubt turned to her own big day as they watched the bride and groom walk down the aisle.
Kate Middleton and her fiancé Prince William were both smiling radiantly as they attended the wedding of their friends Sarah Louise Stourton and Harry Aubrey-Fletcher at the weekend.
Not wanting to deflect attention from the bride, Kate wore a simple black with a sheer neckline teamed with an on trend £310 jacket from Libelula. And completing the look was a pillar box hat, plum cloured heels and a matching clutch.
William – who was an usher - arrived separately at St Andrew's Church in Aldborough, North Yorkshire. He and Prince Harry joined the groom and several friends for an usher's lunch at a local pub before the service.
After the bride and groom said "I do", a vintage double-decker bus took the guests to a reception at Allerton Park, near Harrowgate.
