Lady Gaga revealed she was channelling her inner Willy Wonka as she unveiled her Christmas workshop in New York.
Gaga's Workshop at Barneys New York flagship on Madison Avenue is the retailer's in-store holiday shop, conceived, designed and named by Lady Gaga, selling potential Christmas gifts to her fans.
Gaga said: "It's a Charlie And The Chocolate Factory moment. We wanted it all to be whimsical and fun, with a sense of art and fashion."
Crowds began gathering hours before the unveiling of the seasonal window displays, which Lady Gaga and stylist Nicola Formichetti also designed. They were entertained by a troupe of clowns singing Gaga's hits, including The Edge Of Glory and Born This Way.
The 5,500 square foot workshop on the fifth floor is decorated with an arch-like spider and a gigantic cartoon statue of the superstar herself in a pin-up pose surrounded by jagged mirrors and sitting atop thousands of black plastic discs.
Items on sale include hair bows, stiletto-heeled stockings, studded leather motorcycle jackets for children, Gaga-on-a-motorcycle ornaments, heart-shaped glasses and Little Monster cookies.
Lady Gaga revealed she doesn't have time to do much holiday shopping any more, but said Christmas was a special time in her "traditional Italian house", where the smell of food cooking all day is one of her fondest childhood memories.
Wearing a custom-made ivory gown by Chanel designer Karl Lagerfeld, Gaga said, "Christmas came early. Christmas is today."
Gaga said it was important for the Workshop - open until January 2 - to have a charitable aspect, too, so for each product bought in store or online, 25 per cent of the sales will be donated to Gaga's anti-bullying Born This Way Foundation.
