As soon as that was kind of green-lit, it became very obvious to me what I wanted to do and it was an instinctive reaction to my relationship with how I wear my Ugg boots. Which is in London and in New York, I wear them as soon as I get in basically.

My look is pretty low maintenance, I have a great team around me for hair and make-up, and they have also taught me some great tricks over the years for when I'm doing my own.

I mean, props to Paris Hilton because she's doing it really well and for someone that's such a wealthy heiress she doesn't really have to lift a finger at all. She was the first example of really strong branding and is obviously a very clever businesswoman. I remember recently they printed in a British magazine, they compared her to Kim Kardashian in the sales of perfume and all of this other stuff. She still makes huge revenue from all of her different business endeavors.

If I'm doing my hair myself, I just wash it and let it naturally dry. I'm actually quite good at doing hair; if I wear it up I usually do it myself.

Listen, the idea that I might be a fashion soothsayer is very flattering but completely inaccurate.

My mother isn't particularly vain. Growing up with a parent who put emphasis on personality over looks was important.

My dad cut my hair once - I wanted a bob and he gave me a bowl cut. That was a tough few years.
