I've been a skinny girl my whole life. I just don't sit down - I'm always on the go. It must be down to the genes. We have a healthy body image in my house and great appetites. It'd be hard for you to find a food I don't love.

Sunday night is curry night. I always order a spinach paneer and a chicken tikka. There's usually something good on TV like 'Mr Selfridge' or 'Downton Abbey,' so I'll watch them before I have to think about blowdrying my hair and all the other boring stuff us girls have to do!

Do I sometimes hope I wake up in the morning and people are like, 'What's wrong with her? She looks emaciated.' Of course I would love that. I'm such a clothes whore, I would love the opportunity to be a hanger. But I think I'm more confident than I've ever felt in my life.

I don't think fashion has to change every five minutes. I'd like these to be clothes you can wear for a long time - ten, 20 years; pass on to your daughter. Why buy vintage when you can open your own closet!

Working on 'Austin and Ally' has been an absolute dream! We literally have fun every single day! Whether it's scaring each other or singing together or just hanging out in each other's dressing rooms, the cast and I are super close! I feel really lucky to be with everyone on our set!
