I am always struck, interviewing the planet’s most beautiful women, by the disconnection between their difficult love lives and dazzling looks. Jennifer Lopez, Mariah Carey, Elle Macpherson, Helena Christensen, Emmanuelle Béart, Inés Sastre, Diane Kruger, Sienna Miller — in my decade as an interviewer I have met dozens of these stars and supermodels, and almost invariably they are single or struggling with divorce or some dubious relationship. These women can often seem to have everything — stunning looks, amazing figures, to-die-for wardrobes, killer charm, fame, money — except happiness with men. It is a small, unacknowledged tragedy that I discussed with the supermodel Helena Christensen, who knew all about it.
