[on performing a tribute to Donna Summer at the 2012 Grammy Awards, just 3 days after Summer's death from cancer] I was very emotional out there because I knew Donna Summer and we didn't know she was ill. It was so precious to me. It felt so important to me that we should honour her. She was a very kind woman... and she brought love and light to people.

A lot of my songs are about taking whatever life throws at you and making the most of it.

I don't want to be the next anyone. I just want to be me, now. And that means all different things.

On who she'd like to be stranded on a desert island with: "I'd say Gwyneth Paltrow and Chris Martin. They come across as lovely - so warm, so bright and so talented. I imagine that we'd have great chats. And, if we ever ran out of things to say to each other, I could sing and write songs with Chris Martin, and play charades with Gwyneth. I reckon that they would both be good at strategies and tips for survival as well, which could obviously come in handy if we got stuck there for a long time".

"I know I should keep this a secret, but Céline Dion is something of an icon to me".
