Now the royal fan has admitted he was desperately fearing he and Kate would get caught on the kiss cam!
"I was absolutely dreading they were going to come and show myself and my wife. That would have been very embarrassing," William told the BBC.
William didn't say what he would have done if he and Kate had been egged on by the crowd to kiss for the camera.
It took two tries, but the First Couple finally gave in and kissed with the crowd cheering them on.
