Earlier, Prince William and Kate Middleton, holding each other's hands and gazing into one another's eyes, exchanged wedding vows, turning the commoner bride into royalty and thrilling royal watchers around the world. William, 28, slipped a wedding band made of Welsh gold on the finger of the 29-year-old Middleton.
The bride, wearing a tiara loaned to her by the queen, appeared to marvel at the majesty of the thousand year old Abbey, looking up and smiling as she and William sang along with their guests of friends, celebrities and royalty from other countries. Nearly 400 of the guests are close family and friends.
Earlier, with her face still veiled, Kate Middleton held onto her father and grinned as she walked down the aisle of the ornate cathedral to wed Prince William, the heir to the British throne. A nervous Prince William chewed his lip as his mother, Princess Diana, used to do.
Prince William told Middleton, "You look beautiful" when she arrived at the altar of the church. They exchanged smiles and William leaned over and winked at his father-in-law, Michael Middleton. William reportedly cracked a joke saying, "We're supposed to have just a small family affair," according to a lip reader.
The wedding, watched by over 2 billion people worldwide, delighted the people of Britain. Crowds of at least 600,000 lined the streets to watch the wedding, which is a national holiday. When the couple said their vows, the crowds let out a huge roar and popped champagne bottles.
Royal watchers enveloped in the Union Jack flag, waved and screamed outside of Buckingham Palace as orange balloons floated above them. The Band of Welsh Guards marched along the procession route in their red uniforms and black fur hats. Fans wore sparkly hats and masks of the married couple.

The newly titled Duchess of Cambridge wore a veil with her arms and shoulders covered in lace as she made her vows that turned the commoner bride into royalty.

The crowds who turned out for the event were jubilant, but at least 18 people have been arrested, Scotland Yard reported, and an abandoned car at the intersection of Grosvenor Gardens and Buckingham Palace Road was investigated by explosives officers, the BBC reported.
Middleton's mother, Carole, arrived with her son James. James was the only family member to speak during the wedding. He read a passage from the King James Bible.
Prince William, resplendant in a crimson tunic of the Irish Guards and accompanied by his brother Prince Harry, saluted the guards as the car left Clarence House. William wore a blue sash with his red uniform. The sash represents the order of the garter, the most senior and the oldest British Order of Chivalry. It was founded in 1348.
"He's wearing the uniform of the Irish Guards because he is the colonel of the Irish Guards," said Robert Lacey, royal historian. "He's chosen to wear it because it's going to look very good on the day. Perhaps he knows it's going to match whatever his bride to be is going to wear as well."
Riding in a Bentley, William and Harry cheerfully greeted the excited crowds who lined their route to Westminster Abbey.
"I can hardly believe it actually. I sometimes still think of them as the 15 and 13 years olds that they were…terrible naughty teenagers and here they are young men about to launch into a new chapter of William's life. How exciting," said Colleen Harris, former press secretary to the royal family.
