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 U.S. show The Jubilee Queen with Katie Couric, set to be screened on ABC at 9pm today.

Difficult: '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 said

'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.

'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.

'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.'

In a separate interview for a new ITV1 documentary, the prince revealed how he tore up the official guest list for his wedding to long-term love Kate Middleton last April.

William described the moment in which he was handed a list and did not know a soul on it.

'There was very much a subdued moment when I was handed a list with 777 names on - not one person I knew or Catherine knew,' he said.

'I went to her [the Queen] and said: 'Listen, I've got this list, not one person I know. What do I do?' and she went: 'Get rid of it. Start from your friends and then we'll add those we need to in due course. It's your day.'

Meanwhile, a new biography of the prince has claimed that the future king was so scarred by his parent's failed marriage that he doubted whether he could be faithful to one woman.

Funny: Katie Couric said that both Princes, and 'Prince William especially', were very funny during their interviews

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.

Earlier, Katie Couric had revealed other parts of her interview with Princes William and Harry in the lead up to the Diamond Jubilee celebration in honor of their grandmother Queen Elizabeth's 60 years in power.

The stories that the heirs to the throne shared shows that they have a very close bond with the Queen, 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.
