The wedding dress Amy Winehouse wore when she married Blake Fielder-Civil in Miami in 2006 has been stolen from the house where the singer died. The wedding gown and another frock were slated to go under the hammer to raise money for the Amy Winehouse Foundation charity organization, but instead, they've been reported missing by Amy's father, Mitch Winehouse.

"It's sickening that someone would steal something in the knowledge of its sentimental value," says the 60-year-old father of the late songstress. Metropolitan Police have yet to receive a formal allegation about the thefts, but it's believed they occurred while all of her possessions were being moved out of the house so it could be put up for sale and were not the result of a break-in at the property.

The Fielder-Civil wedding dress and the other garment, which Winehouse wore during an appearance on 'Later... with Jools Holland,' were expected to fetch more than $160,000 at auction in New York. The dress Winehouse wore on the cover of her 'Back to Black' album brought in more than $64,000 last year, and another of her dresses sold for more than $48,000.

"People need to know they are not supposed to be out there on the market and they should not try to buy them," a spokesman for the Amy Winehouse Foundation said of the dresses.
