Kate Middleton was in a second white gown designed by McQueen's Sarah Burton this evening as she left Prince Charles's official London residence, Clarence House, on the way to the big party at Buckingham Palace. Kate Middleton's wedding dress lavishly featured hand-embroidered lace and a nearly nine-foot-long train, but this number was strapless in satin, with diamante embroidered detail around the waist. Kate also paired the piece with an angora bolero! Kate, the new Duchess of Cambridge, left Clarence House with her husband, William, as well as her father-in-law, Prince Charles, and mother-in-law, Camilla. Camilla was in another get-up as well, wearing her second Anna Valentine of the day. The foursome took off for the palace, where Charles is hosting a 300-person private dinner. Charles is due to give a toast, as will Kate's dad, Michael. Queen Elizabeth won't attend the party, which is expected to go into all hours of the night since Buckingham Palace has no closing time! Prince Harry and Pippa Middleton organized dancing for the guests and ensured that there will be food, like bacon sandwiches, for the "survivors" who make it until 6 a.m. Kate and William aren't expected to stay up that late, as they're leaving for their honeymoon tomorrow!

Kate Middleton's maid of honor, little sister Pippa, changed from her white Sarah Burton for McQueen dress and into a green number for this evening's private dinner at Buckingham Palace. Her second dress was designed by British designer Alice Temperley — Pippa was rumored to have been working with Alice for the nuptials, as she and her mom, Carole, were spotted leaving Alice's shop a few weeks ago. Green was a popular color today, as Chelsy Davy wore an Alberta Ferretti suit in the hue and the British prime minister's wife, Samantha Cameron, wore something similar from Burberry. Pippa accompanied Carole, her dad, Michael, and brother James as they headed over to the final event on today's royal wedding itinerary. It's clearly Kate and Prince William's big day, but the festivities of the morning and afternoon have given a new platform to Maid of Honor Pippa. She stunned onlookers in Westminster Abbey this morning with her white frock complementing her tan skin tone and continued to look amazing on her way into the party she was integral in helping to plan.

Kate Middleton and Prince William beamed as they left the royal wedding brunch reception in an Aston Martin. Will was behind the wheel of the car, which was decorated with balloons, a big red ribbon, and a license plate that read "JU5T WED." Kate, still wearing her Alexander McQueen wedding gown, waved to the gathered crowds as they rolled by. The newlyweds' decision to drive themselves was a modern one, as was the car, which Prince Charles had converted to run on eco-friendly, bio-ethanol fuel! The pair's festivities aren't yet over, though. They'll be on hand this evening for a private party hosted by William's father.

Kate Middleton is officially a princess, and she looked every bit the perfect one riding alongside her prince, William, leaving their royal wedding ceremony today. The two waved to the thousands of fans gathered to watch their ride and millions watching around the world. The newlyweds were grinning, sitting side by side, just minutes after exchanging their touching "I dos" in Westminster Abbey in front of all their guests and spending a private moment signing the register. The first kiss is still yet to come, but for now we can't get enough of William and Kate's wedding pictures and all the details of Kate Middleton's Alexander McQueen wedding dress.

David Beckham held onto his top hat as he waited in line to get into Westminster Abbey in London today. Victoria was by his side wearing a navy blue dress from her Victoria Beckham Collection, custom Christian Louboutin heels, and a Philip Treacy fascinator. The couple were among the first group of guests to arrive for the event and mingled in the crowd as they made their way to their seats inside the church. David and Victoria landed in the UK yesterday and brought their boys, Romeo, Brooklyn, and Cruz, along for the trip. Their time overseas won't last long though, since David has to be back in the states to join the LA Galaxy in their match against FC Dallas on Sunday.

Prince Harry left Westminster Abbey in an open top carriage, following William and Kate's carriage procession this morning. Harry looked after page boy Tom Pettifer and bridesmaids Lady Louise Windsor and Eliza Lopes as they made their way to Buckingham Palace after the royal wedding ceremony. Harry played the part of supportive best man perfectly on his brother's big day, even taking a peek at the bride as she walked down the aisle before William did and whispering to the groom how beautiful Kate looks. The bride and groom and their families will soon take to the balcony for the fly past and first kiss, so stay tuned for lots more pictures!

This morning was all about newlywed Prince William, but there were tons more great-looking guys in attendance at today's royal wedding. David Beckham was dashing in a top hat and tie as he arrived with his pregnant wife, Victoria Beckham, Guy Ritchie dapperly turned up for the ceremony, and Prince Pavlos of Greece was handsome throughout the festivities. Prince Harry and James Middleton were also both on hand to show their support for their royal siblings as they wed at Westminster Abbey. Click through to see all of the hot guys at the historic nuptials!

Kate Middleton and Prince William, now officially the Duchess and Duke of Cambridge, greeted foreign dignitaries this afternoon at Buckingham Palace during their brunch reception! It was their second engagement following this morning's royal wedding, and the newlyweds left the palace in an Aston Martin driven by William himself. The car even featured a license plate that read "JU5T WED"! Kate was still wearing her custom-made McQueen wedding gown, though she's apparently already changed into her second Sarah Burton-designed dress. As she and William said hello to guests today, a team of more than a half-dozen bakers were busy putting the finishing touches on the breathtaking cake. The towering confection features eight tiers and hundreds of sugar flowers. Prince Charles will host this evening's party for the couple, and festivities are expected to continue on well into the night. The Middletons, meanwhile, are throwing a small gathering at The Goring Hotel for friends and family not invited to the 350-person palace dinner. Carole and Michael, Kate's parents, will join the royals for the meal once wrapping up their private celebrations at the accommodations where Kate spent her last night as a single woman.
