Because I'm the silly British girl that came to America and just performed with Taylor Swift. I can't wait to show my mum. My mum needs to see this actually. I'm walking to the stage. Taylor invited me to come sing my song Brave with her and I'm really excited and there's a lot of people out there. Los Angeles, say hi to my friend Sara Bareilles. Like this, go like this. What you wanna say and let the words fall out. So we just performed Closer with Taylor. It was really nerve-wracking and exciting. Miss Swift, we'll call her from this point forward.

Los Angeles, this is my hairbrush song. Love my life and my public It's diverse and you can't forget to Stay real, real To me it's like breathing Come on! Everybody over here sing! You
