The stars were out for Elton John’s AIDS Foundation Winter Ball, at the American Embassy in south London. Gemma Arterton, Erin O’Connor and Liz Hurley all looked amazing and other guests did not dissapoint with their outfits with one or two exceptions…. Angela Griffin in a sugary pink unflattering dress and Roisin Murphy who possibly got her invites mixed up and thought she was attending a halloween bash this weekend.
