Demos and Kitty took the roles of Prince William and Kate Middleton as part of the royal engagement celebrations at The Kingsley School.
Pupils at the private school in Warwickshire made a special congratulations card to send to the happy couple.
The young pupils were photographed with the card before it was sent by the Royal Mail to Buckingham Palace.
The school hopes that the fantastic card will stand out from the others as the junior school pupils made the card themselves, as well as including this photograph of the young lookalikes of Prince William and Kate Middleton from the school.
Here’s a photo of the happy couple!
Thank you to Andrew Parker for sending this info!
