Of course she is "military" about what she is eating, so is Victoria Beckham. When you are in the public eye and there are articles about a plaster on your finger

She is very fortunate to have a life of luxury, but there's certainly a lot of hard work involved. There's also help from some kind of beauty help (botox or other) to keep a fresh face which is harder when you are so skinny - and in her case, it's not natural, she wasn't so skinny when she was younger.
Designers must love her, she has as close a perfect shape for their clothes as can be, so good for her.
We have all different body shapes, but we could all be as relatively slim within our shape - if that makes sense. Most of us can't be bothered.
