This year, British comedian Peter Kay - dressed as his alter ego Geraldine McQueen, a wannabe pop star - was the celeb on hand to flip the switch. When he did, the store was lit up with a cheekily gaudy display of an illuminated Father Christmas, stars and reindeer. Paul McCartney also obliged with a musical turn. He and Kay led the crowd, who included Katie Grand, Laura Bailey and Moss' rocker boyfriend Jamie Hince, in a rendition of his hit "Wonderful Christmastime," as an embarrassed Stella McCartney covered her face with her hands at her father's impromptu contribution.
"Another high brow event at Stella McCartney," said the designer with a smile. "And now we're all off to the bingo" quipped Kay. Later, guests crammed into the store to warm up with mince pies, star-shaped "Stella," cookies and mulled wine.
