Mark your calendars!
Prince William and Kate Middleton will wed on Friday, April 29, 2011 at Westminster Abbey.
The hotly-anticipated announcement was first made Tuesday morning via TheBritishMonarchy Twitter account.
After dating for 8 years, William and Kate, both 28, announced their engagement last Tuesday.
Westminster Abbey hosted its share of Royal events: both Queen Elizabeth and the Queen Mother were wed there; the stately monument was also the site of Princess Diana's 1997 funeral.
Jamie Lowther-Pinkington, the prince's private secretary, told the BBC that the pair wanted a spring wedding, and feel that the abbey, despite its huge size, offered intimacy.
"We know that the world will be watching on April 29, and the couple are very, very keen indeed that the spectacle should be a classic example of what Britain does best," Lowther-Pinkington said.
He added that the royal couple are "calling the shots" on their plans, but had a "rather large supporting cast" also offering support.
"Prince William and Catherine have made it very clear that they wish everybody to be able to enjoy the day with them,"Lowther-Pinkington said to the BBC.
Prime Minister David Cameron said that the event will be "a happy and momentous occasion" and that April 29 will henceforth be a national holiday.
Who's footing the bill?
"The costs of the wedding itself will be met by the Royal Household, with government meeting any wider security or transport related costs," Prime Minister Cameron explained.
