I know what I want to look like. I don't want to look trashy. I want mothers to be able to look at me and not have to close their kids' eyes!

I definitely think it [the key to maintain success] is a number of things. It's having the right people behind you. It's having the right work ethic. It's having the right mind-set. And it's also a little bit of luck.

Not yet, but I do wanna work with Leona Lewis. I love her, she's so sweet! I think she's working on her album as well so I'd love to do a nice powerful female duet with her. I think our voices would blend really well. There's a couple of other people I'd love to work with - like Fergie, Justin Timberlake and Alicia Keys.

I'd love to do something with Kelly Clarkson because she's been a monumental influence on me. I love how she handles her celebrity. She's not in the tabloids a lot but everyone knows and respects her because she's got an amazing voice. That's something I aim towards.

I've had lots of friends who've gone through 'Battlefield' situations in their relationships, so when I was singing the song I put myself in their position and tried to imagine what they were going through. I got so, so into it and I think you can tell.

For me, I just never put all my eggs in one basket, so to speak. I know that music and acting now are things that I want to do for the rest of my life. But, if suddenly that was to stop, I'd actually be okay. It's not the be all, end all of my life. I know who I am, outside of this, and I think that's a really big thing to have.

I love being able to sing for my job. I am blessed beyond words and I hope my fans can feel that while I'm on stage!
