Is McQueen's Sarah Burton the Designer of Kate Middleton's Gown?

March 6, 2011— -- It has been the question on the tip of everyone's tongue on both sides of the pond since the royal engagement was announced – who will Kate wear when she walks down the aisle? And now the designer of the dress of the year allegedly has been announced: Sarah Burton, for Alexander McQueen.

Though the princess-to-be is trying to keep the designer of her gown under a tight lid, London's Sunday Times reported today that 36-year-old Burton has won the coveted job.

"A fashion source said that the dress will be a combination of Middleton's own design ideas and Burton's deep knowledge and understanding of high fashion," the Times reported.

Burton, who took over as creative director at Alexander McQueen after the designer's tragic suicide in February last year, is no stranger to showing off her stunning work at high-profile events for world figures.

In the realm of UK royalty, she designed the off-the-shoulder gown worn by Sara Buys, bride of Tom Parker Bowles, son of Duchess of Cornwall Camilla Bowles. And more recently she was behind Michelle Obama's red gown worn at a January White House state dinner.

"I am not doing it," she said, when asked of her involvement with the gown.

Traditionally designers at royal weddings are sworn to secrecy about any involvement in the event.
