I can't stand what people do to each other. I think we're brilliant as a species. I think we are amazing. I think that God is incredible, that He just gave us everything. Everything in our face. Everything for us to use. And sometimes we're such shitheads. And it makes me crazy.

There are so many young women coming up through the ranks. Adele is an amazing singer. Beyonce has great stage presence. She's just a beautiful woman. I love how everyone has just taken charge of their lives and careers.

It was very difficult when I was trying to figure out how to have a marriage and babies and do this at the same time. There was no handbook. You were making it up as you went along.

It's so hard [to be parent] and no matter how old you get and how experienced you get you're always scared you're going to screw it up and you're going to make a mistake.

When you have children your life - this is my job and that's my life. So it's a totally different thing. They're my priority, they have to be, and they always will be. I have to do them first. So this always gets pushed in the back.

I felt I had a responsibility to do the right thing. And then I wanted to do the right thing by my family and there was no handbook.

In my early 20s, I had this idea that I was going to front a band, like Robert Plant of Led Zeppelin. I didn't just want to be the chick singing ballads about somebody breaking my heart. Everyone in the business said, 'Why don't you do what Olivia Newton-Jonn and Linda Ronstadt are doing?' But I wanted to sing as a powerful female who wasn't afraid to speak her mind or be sexual.
