One Direction have been covering quite a few pop classics recently -- first Blondie's 'One Way or Another (Teenage Kicks),' then the Backstreet Boys' 'I Want It That Way.' They're adding another pop heavy hitter to their rotation: 'My Heart Will Go On' by Celine Dion!

The boys covered the 'Titanic' track live in Berlin on Saturday, May 11 following a request via a fan's tweet. Accompanied by piano and shrieking Directioners, the guys admitted to have some issues with the lyrics -- but they still delivered. They sounded darn near operatic at times!
