Royal fans are divided over Archie's christening photos: does he look more like his mum or dad?
The Duke and Duchess released two official photographs to celebrate the event - a black and white photo of Meghan cradling Archie and a family portrait with Prince Charles, the Duchess of Cornwall, Kate Middleton and Prince William.
Meghan's mum, Doria Ragland, and Princess Diana's sisters, Lady Sarah McCorquodale and Lady Jane Fellowes, were also in the shot.
"The Duke and Duchess of Sussex are overjoyed to share the happiness of this day and would like to thank everyone around the world for their ongoing support," read the post.
