Madonna just announced that Idris Elba, the dreamy Luther star who's also a DJ when he isn't acting or addressing James Bond rumors will open her Rebel Hearts Tour stop in Berlin tomorrow night. The 43-year-old Elba whose varied roles have included a drug kingpin on The Wire , the titular icon in Mandela: Long Walk to Freedom, the god Heimdall in Thor and regular old Charles on The Office actually began his career as a DJ long before establishing his name in acting. Madonna's Rebel Heart Tour will touch down in 11 countries in Europe as the Material Girl continues to crisscross the globe.
