A party celebrating the 16th birthday of Prince Andrew?s daughter Princess Eugenie turned into a drunken binge, with the luxurious home of her mother the Duchess of York winding up ?in a real state,? best-selling tabloid The Sun reported

Andrew and his ex-wife had spent 30,000 pounds (44,000 euros) on a ?Pirates of the Caribbean? theme party for their youngest daughter, The Sun said.

Champagne was laid on but the 50-odd high-society guests brought their own hard liquor and the party rapidly descended into a binge. One onlooker was quoted as saying: ?It was completely out of control... there were stains on the carpets and cigarette burns on floors and furnitures. I wouldn?t have wanted to be there when Prince Andrew saw it.? He went on: ?Eugenie and Bea (her sister Princess Beatrice) were clearly concerned, but there was little they could do as everyone was so drunk ?.

An anonymous guest said: ?No one wanted to sit and eat and the drink was flowing. Couples started pairing off and disappearing to dark corners.? Sunninghill Park, a luxury residence worth 10 million pounds (15 million euros), was given to Andrew and Fergie as a wedding present in 1986.

Contract Options, the company in charge of cleaning Sunninghill Park, was quoted as saying: ?It was like a bomb had gone off, the house was in a real state. There were empty bottles and broken glasses. It took all day to clean up.?
