If Kate Middleton and Prince William start producing heirs to the throne soon after the royal wedding, this is what their children could look like.
US forensic artist Joe Mullins has provided a glimpse of the future royal family.
Mullins studied recent photographs of Wills and Kate and used the latest computer technology to predict how their kids could look.
If the couple have a son, the boy who could one day become king is expected to inherit many of William's features, including the famous Windsor ears. Let's hope he has this cheeky grin.
Perhaps luckily for her, a daughter is predicted to favour Kate's looks, with a high forehead, slightly pointed chin and long brown hair.
Do your children look the spit of one of you?
Are they a merging of both your looks and character?
Or are they completely their own people?
