"I understand that The Duke and Duchess of Cambridge have visited their new nephew Archie today at Frogmore Cottage. The visit took place after Harry returned from a day of engagements in Oxford."
It is not yet known if William and Kate took their three children, Prince George, Princess Charlotte and Prince Louis along for the special occasion.
Earlier this week it was reported that George, Charlotte and Louis were "dying" to meet Uncle Harry and Aunt Meghan's bundle of joy.
"Prince George and Princess Charlotte have already been asking their parents when they can meet their new cousin, they are as excited as anybody," a source told the Express.
William and Kate's visit couldn't have come at a better time as the Duchess was given cuddly toys for Archie today while visiting Bletchley Park to view a new exhibition in the restored Teleprinter Building.
