A leading British newspaper is reporting that Sarah Burton, creative director of the Alexander McQueen fashion house, has been chosen to design Middleton's wedding gown.
While both Burton and the company's CEO deny the report, experts say it does not necessarily mean the McQueen house has not been chosen.
Just two weeks ago, British Fashion Council chief executive Caroline Rush told The Associated Press that whoever had been chosen would be bound by the terms of the agreement to do everything possible to keep their role secret until Middleton walks down the aisle before the eyes of 1,900 invited guests and a vast global television audience.
Burton, 36, worked closely with McQueen for years and was hailed as "a brilliant choice" for the top job at McQueen by American Vogue editor Anna Wintour.
Burton is British, which would satisfy those hoping Middleton will choose a British designer, and under her leadership McQueen has maintained its reputation for dramatic design and phenomenal craftsmanship.
Palace officials refused to comment on the report.
