"Good Morning America" caught up with Prince William at his day job at the RAF Valley in Anglesey, Wales to drill him on his pre-wedding jitters.
When asked what keeps him up at night, Wills laughed, "The whole thing. How's that? We did the rehearsals the other day and my knees started tapping quite nervously, so it's a quite daunting prospect, but very exciting. I'm looking forward to it but there's still a lot of planning that needs to be done in the next four weeks."
Of his top secret bachelor party, William remarked, "It was a military operation and my brother and I were quite proud about how it went."
The reporter added that William's RAF buddies reportedly make him drink his tea out of a William and Kate wedding mug.
