With nearly 2 billion viewers watching from around the world, Prince William, 28, and Kate Middleton, 29, exchanged their vows. Instead of the traditional "I Do," the royal couple chose the words, "I Will."

The ceremony, conducted by the Archbishop of Canterbury, ended with the words, "I pronounce that they be man and wife together!"

Prince William's cousins Beatrice and Eugenie showed up to the royal wedding this morning wearing fashion-forward outfits topped by avant garde Philip Treacy hats which were described as "comical" but many critics.

Princess Beatrice wore what could have been a very understated Valentino Haute Couture taupe dress with matching jacket, but she topped it off with an oddly shaped Treacy hat in a matching color that pulled focus away from her demure dress and put it squarely on her unflattering headpiece. The hat has already inspired a Facebook page devoted entirely to the beige disaster, called Princess Beatrice's Ridiculous Wedding Hat. As of press time, the group has more than 5,000 fans, many of whom called it "dreadful", "Mickey Mouse ears", or a "pretzel."

As for Eugenie, she didn't fare much better in her tight Vivienne Westwood suit and poufy asymmetrical skirt that emphasized her hourglass figure.

The girls are known for be fashion risk-takers ... but in this case, I don't think the risk paid off!

In fact, Beatrice, who appears to have dramatically slimmed down for the wedding, has looked better wearing practically nothing at all! Check her out in a royal blue bikini last summer in St. Tropez ... after the jump.

Kate Middleton's royal wedding gown looked nothing short of spectacular as she walked down the aisle at Westminster Abbey this morning.

The Duchess of Cambridge chose to wear a classy, yet sexy Alexander McQueen wedding dress. Stunning!

Vogue Contributing Editor Sarah Mower said the following about how the designer's name was kept under wraps:

“Catherine Middleton and Sarah Burton have successfully kept the best-guarded secret in fashion history. The incredibly moving moment when the new Duchess of Cambridge stepped out of her car in an Alexander McQueen dress was the fantasy everyone in fashion has been dreaming would come true.”

David and Victoria Beckham wore matching dark blue outfits for the royal wedding -- Victoria one of her own designs and David in tails and a top hat.

Vic donned a "fascinator" hat by Philip Treacy, also word by Prince William's cousins Princess Beatrice and Eugenie of York. David wore a suit by Ralph Lauren.

The Beckhams were two fo the 1900 guests because David worked with then Prince William on England's World Cup bid.

Prince William and Catherine Middleton exchanged vows at Westminster Abbey in London Friday, taking the new titles of Duke and Duchess of Cambridge.

Kate, 29, wore a custom gown by Sarah Burton for Alexander McQueen which featured a 6-foot-long train. William, 28, was waiting for her at the altar and mouthed the words, "You look beautiful," when she arrived to meet him.

The Archbishop of Canterbury conducted the ceremony and the couple exchanged "I will"'s instead of "I do"'s. And per royal tradition, the couple didn't kiss at the altar. They saved the smooch for the balcony of Buckingham palace, before all their fans

Amber Rose had a lovely girls' day out on Robertson Blvd., and the curvaceous beauty looked like she had an absolute blast shopping for goodies at Chanel, posing for pics with fans, and grabbing some exquisite grub at the Ivy restaurant.

If you're a celeb who wants to get your picture taken, this is definitely the restaurant to hit!

It's recently been reported Kanye West's ex is gearing up to film her own reality show for VH1, although the network has yet to confirm any plans for a future series.

With only six contestants left to compete for the coveted mirror ball trophy, Dancing practices are getting that much more intense!

Thankfully the stars don't looked stressed at all. Kendra greeted the photogs by doing a little impromptu dance in the parking lot, and Chelsea Kane flashed us one of those mega-watt smiles we love so much.

We really can't get over how much weight Kirstie Alley has lost this season! We're happy to see the actress hasn't fallen under the "Bristol Palin Curse" where she progressively gains weight during the show, instead of losing it. We still don't get how that's even possible.

Next week's show will feature the remaining cast performing two dances each.

Would will be eliminated next?

Richie Sambora is checking himself into rehab for exhaustion and to regain his sobriety, after ending his tour with Bon Jovi.

The 52-year-old guitar player and his group are scheduled to play tour dates this month in the U.S., before heading to tour in Europe through June.

Sambora's bandmates said in a statement: "Our support for Richie is absolute. He is, and will remain, a member of Bon Jovi. Although he will be absent from upcoming shows for the time being, we very much look forward to his healthy return. In the meantime, we will keep our commitment to our fans and continue our tour."

Sambora entered treatment for alcoholism at ULCA Medical Center in 2007, two months after his nine-year marriage to Heather Locklear ended, and the passing of his father due to lung cancer.

Coincidentally, Richie's decision to seek treatment comes on the heels of his probation ending last week.
