I have this whole thing: if you look good, you feel good, and if you feel good, you look good.

For an hour every day, I did something. I was on the elliptical or the treadmill, and if someone asked me to go to a class - whether it was spinning, boxing, yoga, you name it - I went. By the end of the month, I felt so good, I just kept going. I didn't want to lose my momentum.

I've spoken to people who I swear can tell the future.

I'm going to get up every morning at 6:30 to work out. Then, when I've kept with it all week, I give myself something I really want, like a new handbag or a piece of jewelry I'm coveting.

I do try to watch it. I'm not saying you have to put yourself on a diet, because I hate the word "diet." But it's more of, like, having a balanced lifestyle makes me feel better. I try to do one to two days with no meat. I try to lessen my gluten. Those are things that I struggle with.

I think I've done every crazy diet there was in the beginning, but it's weird: I'm thinner now than I was when I was modeling. I don't obsess about it.

So a lot of people are like, "What are you thinking? Why are you buying size 10?" Well, I'm 5 feet 9 1/2 inches and a size 4. Even though that's what I wear, between a 4 and a 6, a 10 sometimes hangs better on me. Especially the not-as-good materials.
