Leona Lewis

I think when people see that you are shy, or even just calm, collected and reserved, they think you can be pushed around, made to do everything they want - but that's definitely not true of me. The people closest to me know that's not the case. They know I'm not a pushover.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

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!
