The biographer also wrote that nerves were high on the day of the wedding, despite William’s joke.
William is believed to have said to the Bishop ahead of Kate’s arrival: “Make sure everything’s alright. It’s beautiful the way it is.”
The Duke also was shocked by the size of the crowd, and said: “It’s mad, it’s mad!”
Prince Harry served as William’s best man, with the Cambridge royal telling his brother: “All I have to do is get my lines right.”
