I think a lot of young teenagers try to get esteem from accolades from other people, or boys, and what you learn as you get older is that you have to create that within yourself.

I try to work out with my personal trainer for an hour, four times a week - we mainly concentrate on weights and running. If I'm on the road I sometimes do DVD work-outs in my hotel room - P90X and Insanity are a couple of my favourites.

A lot of times on tour it's about, 'OK, where am I today? Wow, I'm in Costa Rica. What is their famous dish?' And it's about trying the food, and really experiencing it.

I've had such a great run with The Dutchess...and now this. You know, it is so interesting how in this business, the second you start dating they want to know if you're engaged. The second you're engaged they want to know when you're going to be married. The second you're married, they want to know when you're having children.

I remember having no money and debating whether I should go get fast food or eat at Mom's for free. Now I'm going to these fancy places on vacation and ordering room service. I treat myself because I remember not having it.

I'm not going to lie: There are times I play mind tricks on myself, like that the french fries are poison. With desserts, I'll let myself have just one bite, but I'll look like a freak when I'm eating it, like when I did Duncan Hines commercials as a kid, just savoring every morsel.

It was the hardest boyfriend I ever had to break up with.
