Lily Allen was at Selfridges yesterday celebrating the 100th year of the store. She celebrated alongside London Mayor Boris Johnson, Joan Collins, Erin O'Connor, Jodie Kidd and many others, looking cute in her black outfit and green jacket. Lily will also be celebrating her own news as she's set to be featured in new Chanel adverts. She'll be photographed by Karl Lagerfeld for a handbag ad campaign next week, Karl said he picked her because, "She's fun". Congratulations Lily!
