Prince William has revealed how he'd wished that his mother Princess Diana had been able to see his wedding day.
The prince said it was the 'one time' since she died that he'd really missed his mother and he'd felt 'sad' knowing she wouldn't be there.
William opened up during an interview at Clarence House, where he lives with Kate, for the U.S. show The Jubilee Queen with Katie Couric, set to be screened on ABC at 9pm today.
'I sort of prepared myself beforehand so that I was sort of mentally prepared,' he said. 'I didn’t want any wobbly lips or anything going on,' Prince William told Couric in the interview ahead of the celebrations in honour of the Queen's 60-year reign.
'It was 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.
'I think she would have loved the day and I think, hopefully, she’d be very proud of us both for the day. I’m just very sad that she’s never going to get a chance to meet Kate.'
For Harry too it was a poignant moment, as he felt his mother's absence acutely, knowing especially that 'she would have loved Kate.'
'I think she had the best seat in the house probably,' Harry said. 'She would have loved to have been there.'
Harry, who acted as his brother's best man, also confessed he was 'massively nervous' on his brother's wedding day.
'Everybody was nervous,' he said. 'The whole thing was a bit of a blur to be honest because there was God knows how many millions or billions of eyes focused on us. Luckily, mainly those two.'
The two billion pairs of eyes didn't go unnoticed by William either. Recalling his wedding day he said: 'Honestly it was one of those days where you feel very elated. Also completely terrified, I have to be honest. The prospect of two billion people watching was quite daunting.'
A new biography of the prince has claimed that the future king was so scarred by his parent's failed marriage that he worried whether he could be faithful to one woman.
According to royal biographer Penny Junor, the author of 'Prince William: The Man Who Will Be King', Prince Charles and Princess Diana's highly publicised affairs contributed to Prince William's delayed marriage proposal to now-wife Kate Middleton.
'The problem was William: he had very real worries about whether it was possible to love just one woman. After his hurricane childhood, he was understandably cautious about committing to a relationship,' Junor writes in the book.
Katie Couric, who later confessed she had been 'trepidatious' to bring up the subject of Diana because it was 'so personal and private', also talked to the princes about their relationship with the Queen.
The stories that the heirs to the throne shared shows that they have a very close bond with her, one that is much more normal than expected.
'I still think she's just my grandmother, really,' Prince William told the American interviewer when asked if he remembers a specific moment when he realised that his grandmother was not like everyone else's.
