The Duchess of Sussex shared a collage of photos to celebrate her husband's 35th birthday on Sunday (15 September), including a previously unseen picture of baby Archie. Meghan posted the image to the couple's Sussex Royal account along with a very sweet message.

The Duchess shared a grid of nine photos of her husband, from him as a baby to him on his wedding day and one picture with his son Archie at his Christening, where Meghan could be seen holding the baby while Harry knelt down beside them.

"Your service to the causes you care so deeply for inspires me every day," Meghan wrote in the caption. "You are the best husband and most amazing dad to our son. We love you ❤️Happiest birthday!"
