My thighs were huge; they were like rock! Growing up, I was really athletic, and I had a very athletic body.

I usually do my hair and makeup in 30 to 45 minutes, and if my hair is dirty, I'll just put it in a bun or a ponytail. If it's in a bun, I'll part it down the middle and do a low bun with a couple pieces in the front coming down.

My Pirelli calendar is hanging on the wall of my friend's frat house, and he doesn't know anything about fashion. That balance is what leads to big campaigns outside of fashion. But I never want to choose one or the other. Both commercial and high fashion are what make my job so interesting.

I will be the first to say, when I started, I was the worst on the runway ever. I feel like I try to keep learning every time I step off a runway; I try to get better with each one. I hope that I'm getting better as I go - it takes a few seasons to get your Karlie Kloss walk on.

We are a rugby family really. My dad and both granddads played rugby. Dad was good, on his way to Bath until he broke his leg. My brother Harry got an invitation to go and play for Bristol. I go and watch Sale Sharks and have been to Twickenham a few times.

Yoga disciplines both the mind and the souls and not just your body. It helps me in having a constant positive outlook in life. I would love my family to adopt this form of fitness as well.

The difference between our family and other poor families was that my mother actively chose to be poor. She was highly literate, and she had a college degree, but after my father left, she took the first secretarial job she could find and never looked for other employment again.

We're both getting older, our children are starting to leave home. But I can say that I'm just as passionate a songwriter now in my 50s as I was in my 20s. But instead of talking about the general kind of angst that I felt as a teenager, I'm writing about more specific issues.
