The real question is, what does she wear to the gym? (It transpires that she works out "all the time", and she is very wiry, although she says she takes a "stack of newspapers" in the taxi with her to the gym, which suggests she may not exactly be caning it on the treadmill.) "Not diamonds," she laughs. "Normal stuff.
A Rick Owens white T-shirt and black leggings. I'm not high-maintenance. When I think my hair needs a bit of help, I just glue another bit on to my head." It is a life less ordinary, but it fits her perfectly.
