Princess Di is my sister, she just won't admit it.

When I see 16 year-olds waiting for me, I just want to spank them and give them guitars and tell them to start bands. It's a bummer that girls have to respond to rock artists sexually instead of, like, 'wow, me too!'.

My mentors are people like Cameron Crowe and Carrie Fisher.

On Sofia Coppola's 16th birthday, way back in 1987, I stole a lip gloss from her Sistine Chapel of a bedroom. Years later, I left a Chanel lip gloss in the reception of the Mercer Hotel for her. You know why? I believe that you've got to fix your karma.

In rock 'n' roll it's really about being as vulnerable as possible and giving them what they want. But onstage it's about pausing, about internal life, it's about internal triggers - that's one of the reasons I'm really challenged to do a play.

Only dumb people are happy.

I cannot exist as a solo artist.
