why she wont make another movie

I don’t want to sound ungrateful, but my mission in life is music - and I’m firm with it. That’s how I felt before the film. Doing the music and the whole thing felt creative, and that’s why I made an exception. These people who do music and are amazing actors, I don’t agree with that. I’m stubborn and loyal, and music has saved my life 9,000 times.
