The groom's family announced the long-awaited engagement and upcoming wedding today.
The world's most eligible bachelor proposed to his girlfriend of eight years during a safari in Kenya in October.
According to the official statement, "The Prince of Wales is delighted to announce the engagement of Prince William to Miss Catherine Middleton. The wedding will take place in the Spring or Summer of 2011, in London. Further details about the wedding day will be announced in due course.
"Prince William has informed The Queen and other close members of his family. Prince William has also sought the permission of Miss Middleton's father. Following the marriage, the couple will live in north Wales, where Prince William will continue to serve with the Royal Air Force."
A Buckingham Palace spokeswoman said: "Both the Queen and the Duke of Edinburgh are absolutely delighted for them both."
At a fashion show in 2001 the future king of England was overheard telling a friend that he thought Kate was "hot" when she modeled a see-through dress with black lingerie underneath.
Many of the couple's wedding plans are still unknown, but it is expected that Prince Harry, Prince William's younger brother, will act as best man and the details of the wedding will be organized by Clarence House, which oversees Prince Charles' and his sons' affairs.
