“I sort of prepared myself beforehand so that I was sort of mentally prepared,” William told ABC's Katie Couric while adding, “I didn’t want any wobbly lips or anything going on.”
The 29-year-old lost his royal mother on August 31, 1997 during a fatal car crash and while William prepared to wed, he admitted, “It’s the one time since she’s died, where I’ve thought to myself, ‘It would be fantastic if she was here,’ and just how sad really for her, more than anything, not being able to see it.”
William and Kate recently celebrated their one year wedding anniversary on April 29th, and the Prince agreed with his brother, Prince Harry, when he said their mother "had the best seat in the house" on the day of the royal wedding.
“I think … she would have loved the day and I think, hopefully, she’d be very proud of … of us both for the day. I’m just very sad that she’s never going to get a chance to meet Kate," William told Katie.
Check out a sneak peak of the exclusive interview with both Prince William and Prince Harry before "The Jubilee Queen" with Katie Couric airs tonight at 9PM ET on ABC.
