The Duke and Duchess of Sussex celebrated the christening of baby Archie yesterday (Saturday July 6).
As the gorgeous official family photo was released, close family gathered for the snap.
But eagle-eyed royal fans noticed something in the background.
Prince William's face.
The photo, which showed Prince Harry and Meghan Markle in the foreground holding baby Archie, also featured Prince Charles and Camilla, Meghan's mum Doria, and Princess Diana's sisters Lady Jane Fellowes and Lady Sarah McCorquodale.
On the right-hand side of the group was the Duke and a very glam Duchess of Cambridge.
But fans noticed William's pursed lips and something strange about his smile, and wondered what was wrong with the Duke.
One fan wrote: "William doesn't look happy at all! And Kate has a forced smile on her face."
William doesn't look happy at all!
"Omg Wills face," another commented, followed by a series of cry-laughing and thumbs up emojis.
A third wrote: "What's wrong with William's face? He big [angry emoji] about something?"
