Actually, dittany, I don't like the implication that something bad must have happened in her life. We don't know that it did and the article makes the point that she didn't have a stereotypically disadvantaged childhood.
I don't like the idea that somehow, if she'd been more obviously disadvantaged, if she could dredge up and share some horrible formative experiences, it'd all be ok. It's not really our business why she drank like that, imo.
It reminds me a little of the coverage of the girl who was sleeping with - was it Wayne Rooney? - who turned out to have had quite a posh upbringing despite ending up as a call girl. The papers were all over the story and it seemed uncomfortable - as if it's somehow ok if disadvantaged girls end up as alcoholics or prostitutes?
