I remember so vividly the first song I ever wrote. It was called 'Different People.'

I had gotten pregnant with Apollo, and I didn't plan on that - it was just such a beautiful miracle. Four weeks later they called me and, like "Do you want to do The Voice?" It was this incredible opportunity to do something different.

I had done the No Doubt record Push and Shove, and that was a real challenge for me: I think after the giving birth twice, going on multiple tours, all the stuff that I had done, I really got quite burned out after that.

Before, I was really passive, all I cared about was being in love with my boyfriend. I didn't have any creative power, nothing. I don't know that person any more.

There's nothing that compares to being in a band with your best friends. We're so comfortable together, we understand each other. It feels, like, normal. Whereas solo period felt like I was trying to be something, and play a role, and pretend.

At first it was my brother's songwriting and I was just doing what everyone told me.

People can say whatever they want to about me... and I don't get too affected. But I didn't want them to think I was a failure.
