I was backstage at the House of Blues in L.A where I was about to perform, and Stevie Wonder and Prince turned up at my dressing room together! Stevie started beat boxing and Prince started singing one of my songs, all of a sudden it was like I was in a cypher with these incredible artists.

A woman is more than the sum of her parts.

My only job is to be happy. So for everybody that cares about me and is not trying to be all up in a celebrity's business, just know that I'm happy. My son is happy. We enjoy our lives.

People is, I think, it's their nature - some people's nature, in a way, to be angry or jealous or just spiteful about somebody else's blessings.

Balancing is hard. I've lost roles that I really wanted because I had set up a tour. I cancelled tours to do roles before. But I have to find the time to make that up to my audience. I made a commitment to them.

All I have to do is be me on stage. But acting, I have to be someone else, and walk how they would walk and blink how they would blink. I used to talk about it bad like, 'Aw man, that person made $10 million a movie?' But now I understand why they do. I get it now.

My grandmother told me: 'Never be in debt to anyone or anything.' Which is probably why I've never been financially extravagant - I still go to Costco. I'm always conscious of living within my means.
