After months of international speculation, the beautiful Kate Middleton revealed the winning wedding look Friday as she walked into Westminster Abbey to marry Prince William.

Her vintage-inspired v-neck ivory gown by Alexander McQueen's Sarah Burton featured long, lace sleeves and a sweetheart style bodice. The bodice, skirt and underskirt were constructed out of French Chantilly and English Cluny lace while the skirt was a luxe ivory and white satin gazer.

Forget Bruce Oldfield, Sarah Burton and Victoria Beckham.  Kate Middleton's bridal gown is being designed by Sophie Cranston of the Libelulu label.

Cranston, 34, has been a rising star but is still a relatively unknown name; that is until now, thanks to the Huffington Post which broke the story.

Sophie was given the Designer of the Year Award at London's Graduate Fashion Week in 1999 and later honed her design skills under the late Alexander McQueen.

Kate Middleton has long been a fan. She wore one of Cranston's designs to a wedding last January.

The black velvet coat dress with diamante clasp Kate wore that day did not receive nearly as much attention as some of the other outfits she's been photographed in, but Kate was obviously sold.

Since launching her Libelulu label in 2002, Cranston has attracted a handful of other famous followers, including Harry Potter's Emma Watson.

ROYAL WEDDING: Prince William Invites Fly Boy Buddies To Nuptials

Legendary fashion designer Oscar de la Renta has taken First Lady Michelle Obama to task because of the gown she wore to the state dinner for Chinese President Hu Jintao, RadarOnline.com has learned.

“My understanding,” de la Renta told WWD, “is that the visit was to promote American-Chinese trade — American products in China and Chinese products in America. Why do you wear European clothes?”

Mrs. Obama wore an elegant red-to-black gown designed by Sarah Burton from the late Alexander McQueen’s design house.  McQueen was British as is Burton, and de la Renta thought Mrs. Obama should have only worn a gown that was made in the U.S. of A.

Even though Mrs. O is the first First Lady in 30 years not to have de la Renta design for her, he insisted his criticism wasn't based on that.

"I'm not talking about my clothes, my business," he said. "I'm old, and I don't need it. But there are a lot of young people, very talented people here who do."

Comedienne Joan Rivers revealed she once ditched a joke about First Lady Michelle Obama from her stand-up routine - because she feared she'd be accused of racism.

Recalling the wisecrack to shock Jock Howard Stern, the comedy legend said: "We used to have Jackie O now we have Blackie O!"

The audio can be heard here on RadarOnline.com.

Rivers wrote the quip about President Barack Obama's wife in reference to her fashionable dress sense and comparing her to former First Lady Jackie Kennedy Onassis.
