The 28-year-old prince, who is second in line to the British throne, and Middleton, who turns 29 on Sunday, will marry on April 29, which will be a national holiday in Britain. More details of the impending nuptials were released today.
"Prince William and Miss Catherine Middleton have made more decisions on their upcoming wedding," St. James's Palace said on Twitter.

The wedding begins at 11 a.m. and the bride will be conveyed to Westminster Abbey by car.
In 1981, Lady Diana Spencer traveled in a glass coach to St. Paul's Cathedral for her wedding to Prince Charles. Thousands of people lined the streets to get a glimpse of the bride.
The BBC said Middleton did not want the "pomp and lavishness""that a carriage would involve, but Majesty magazine Editor-in-Chief Ingrid Seward called it "a great shame" that the public wouldn't get to see the bride in a Cinderella-style glass coach.
After the ceremony, the couple will travel to Buckingham Palace in a carriage procession in a route that will include Parliament Square, Whitehall, Horse Guards Parade and The Mall. And yes, the newlyweds are expected to make an appearance on the balcony of Buckingham Palace.
"The news that the wedding procession will follow the traditional route in Westminster will thrill all those who plan to catch a glimpse of the royal couple as they start their life together," Colin Barrow, head of the Westminster City Council, told the Press Association.
William's private secretary, Jamie Lowther-Pinkerton, said the couple were "very mindful" that it would be unseemly to be too ostentatious in tough economic times.
Later in the evening, Prince Charles will host a private dinner at the palace, followed by dancing.
It's traditional for royal nuptials to be followed by a wedding breakfast, not a big reception. But William and his bride seem to be determined to put their own stamp on the proceedings.
The queen, Prince Charles and the Middleton family are paying for the wedding, but taxpayers will have to pick up the cost of extra security for the event.
