So here's the 'Future King of England', with the other two 'Future Kings of England', alongside the woman who's going to outlive them all - their mammy, grandmother and great grandmother - Queen Elizabeth.

She's turning 90, don't you know, so herself and her heirs have posed for a series of commemorative stamps. And, in case you're wondering how Prince George got so tall and he's not even 3, here's his secret...

That smile. Those shorts. We could scarf him whole!

And in case you were wondering what he was standing on, it's not books but "high density foam blocks".
