While the Duke and Duchess of Sussex live just minutes from St George's at Frogmore Cottage in Windsor, Meghan is currently on maternity leave.
The Duchess welcomed her first child, Archie Harrison, just 11 days before the wedding on May 6 and is undoubtedly enjoying downtime with her newborn royal baby.
Prince Harry, 34, arrived with Peep Show actress Sophie Winkleman, who is the wife of Lady Gabriella's brother Lord Frederick Windsor.
Also missing from the festivities were Prince Charles and wife Camilla, as well as the Duke and Duchess of Cambridge.
Despite her absence, Kate's family were guests at the wedding.
Her parents, Carole and Michael Middleton, attended with younger sister Pippa and her husband James Matthews.
