The couple - who will now be known as the Duke and Duchess of Cambridge - exchanged their vows in front of the Archbishop of Canterbury and hundreds of family members, visiting dignitaries and invited guests shortly after 11am this morning (29.04.11).
As expected, Kate did not promise to "obey" her husband when she said her vows, but contrary to some rumours, the pair exchanged traditional sentiments, rather than penning their own verses.
According to a lipreading expert, William cracked a joke with Kate's father Michael Middleton when they arrived at the alter, saying: "We're supposed to have just a small Family Affair."
After the ceremony, the congregation sang 'Love Divine All Love's Excelling', before the bride's brother James Middleton gave a reading from Romans 12, 1, 2 and 9-18.
The choir then led the congregation in singing 'This Is The Day', which was specially composed for the occasion by John Rutter and comprising different psalms from the Bible.
The Right Reverend and Right Honourable Dr. Richard Chartres, Lord Bishop of London and Dean of Her Majesty's Chapels Royal then addressed the couple in a 10 minute speech, before the choir sang another hymn, 'Ubi Carita Et Amor'.
Prayers were then said, followed by a rendition of 'Jerusalem' before the ceremony ended with The National Anthem and the couple signed the three registers.
