I’m really superstitious. First I’ll warm up, drink lots of tea, hang out with my band. If people in the room have anything in their cups, they aren’t allowed to cheers. Not just before a show, but ever. Before a show in Stockholm, my band thought it’d be funny to cheers with water before our show. I was so mad at them, and we went onstage and literally everything went wrong. Everything. Before my Brit Awards performance, I was so worried that I was gonna jinx my performance by being so nervous—so I wore my knickers inside out, under my outfit.
