As his wedding approaches, Prince William has confessed to being so nervous his knees were knocking in a wedding rehearsal.
The 28-year-old, who is due to tie the knot with fiancee Kate Middleton on April 29, admitted he had had sleepless nights about "the whole thing", but was looking forward to the big day.
William made the comments after demonstrating his work as a Search and Rescue (SAR) pilot on a training exercise out of RAF Valley, where he is based.
The royal, who joined C Flight, 22 Squadron in September, has already participated in 12 operational search and rescue missions - a similar amount to any of his contemporaries.
But rescuing people from life-threatening situations is not the only nerve-wracking element to the Prince's life.
When asked what elements of his impending wedding day were giving him sleepless nights, he said: "The whole thing!"
"I was telling everyone I did the rehearsal the other day and my knees started tapping quite nervously. It's quite a daunting prospect but very exciting and I'm thoroughly looking forward to it but there's still a lot of planning to be done in the last four weeks."
Speculation has been rife this week over where William celebrated his stag do, confirmed to have taken place over the weekend.
But the royal refused to be drawn on any details, despite admitting being slightly smug over outsmarting the media. "It's quite good news always to outfox the media but it was a military operation and my brother and I are very proud of how it went," he said.
William, who got his helicopter wings in January last year, has completed around 35 operational SAR standby shifts at RAF Valley - each shift lasts 24 hours.
