Before embarking on her 2001 Drowned World tour – her first since 1993 – Madonna performed a show at New York's Roseland Ballroom in a T-shirt giving a nod to another chart-topping lady. "Britney Spears became my talisman for the week," Madonna told Elle in 2001. "I became obsessed with wearing [Britney] T-shirts. I slept in them, as well. It was like I felt it would bring me luck. And it did."
