No sooner had women got hot under their collars about the 'sacking' of the fortysomething Isabella Rossellini from Lancome adverts than she is back. This time around she is in Donna Karan's latest ad campaign, joining the established 'face' of Donna Karan, the grown-up model Rosemary McGrotha. Also in the new campaign, shot by Steven Meisel, will be the model-turned-actress-turned- 40 Donna Mitchell, the journalist Benedetta Barzini, also in her forties, and the supermodel Linda Evangelista who, according to her agency, is 29.
