Like many brides, the Duchess of Cornwall experienced nerves in the lead up to her wedding day.
But it wasn't the guest list or the table arrangements that were keeping Camilla up at night, it was how the world would react to the impending vows.
As she and Prince Charles had both been married before, and his late wife, Princess Diana had been the nation's sweetheart, it was no surprise that Camilla was nervous on the big day.
Charles and Camilla were on-off lovers for many years and finally tied the knot in civil service at the Windsor Guildhall back in 2005.
Speaking on the Channel 5 documentary Charles and Camilla: King and Queen in Waiting, royal expert Jenny Bond said: "I think Charles has always wanted to make Camilla his bride, his wife.

"I think he felt that she had endured a lot of really negative criticism over the years and she had taken it with a lot of dignity and all he wanted was to make her his wife."
But Camilla was reportedly "terrified" that nobody would be waiting outside after the couple walked out as husband and wife
"Having once been widely reviled as an adulteress, she was almost paralysed with fear," biographer Penny Junor explains.
Current affairs commentator Carole Malone added: "She was terrified no one would come, she was terrified she'd be booed."
"I remember seeing this film footage at the time at about 6am and there was no one on the streets of Windsor. It was freezing as well I remember, it was a really cold day.
"As a journalist I was looking at it and thinking, the only reaction to this is going to be national apathy, which is almost as bad as protest.
"However, by 10:30am the streets were thronging with people."
As the day went on, Camilla began to relax, reassured by having her friends and family around her.
William and Harry stood alongside Camilla's children Laura and Tom as the couple said their vows.
The Queen weren't present at the civil ceremony, because of her "disapproval of the arrangements, not of the marriage," said her biographer Robert Hardman, according to the Express.
However, she was at the church blessing at St George's Chapel shortly afterwards.
When Camilla married Charles, she technically became the Princess of Wales, however, she decided not to use the title out of respect for Diana.
Instead, she used the secondary title the Queen handed her on her wedding day - the Duchess of Cornwall.
