Supermodel Iman will be taking it easy this Christmas after reportedly undergoing foot surgery.

Sources tell the New York Post's Page Six column that the 58 year old is being nursed back to health by her husband, rock icon David Bowie, who has been looking after the beauty as she recovers from a mystery procedure.

News of the operation emerges more than a year after Iman revealed she had fractured her foot, an injury which forced her to temporarily quit wearing high heels.
