Prince William and Duchess Kate: A birthday post for sister-in-law Meghan

Prince William (40) and his wife, Duchess Kate (40), congratulate their sister-in-law, Duchess Meghan, on her 41st birthday. "Happy Birthday to the Duchess of Sussex!" reads a story on the Cambridges' Instagram account.

In addition, they have published a particularly pretty portrait photo of the jubilee from her last stay in Great Britain. It shows her at the memorial service to mark the 70th anniversary of Queen Elizabeth II's throne in early June at London's St Paul's Cathedral.

A few minutes after the Cambridge post, Prince Charles (73) and his wife Duchess Camilla (75) also joined the congratulations. They also posted a photo from the London event against a green background and captioned it, "Happy Birthday to the Duchess of Sussex!" along with a balloon emoji.

Prince Harry (37), William's brother, has lived with his wife Meghan and their two children Archie (3) and Lili (1) in their native California since the beginning of 2020. They had previously resigned from their offices and duties as senior royals.
