“Christmas is about having a great time with your friends and enjoying yourself,” Stella told us at her annual Christmas lights party at her Bruton Street store. The designer’s father, Sir Paul McCartney, was there to celebrate with his new wife Nancy Shevell, as was Kate Moss and the Absolutely Fabulous Edina Monsoon (Jennifer Saunders in a shiny gold Stella coat), who told Alexa Chung, “I didn’t know who you were at first, but now I do, someone told me,” before turning on the store’s Christmas lights.
