One Direction fans were in for a surprise at the boy band's weekend show in Berlin.
The UK teens did an impromptu performance of Celine Dion's 1997 hit, "My Heart Will Go On," in the middle of their set of 1D songs. The boy band performed the song, which was originally recorded for the film "Titanic," to a packed crowd of screaming fans -- take a look in the video above.
Made up of Niall Horan, Zayn Malik, Liam Payne, Harry Styles, and Louis Tomlinson, One Direction has performed covers of hit songs before. The group did a rendition of the Backstreet Boys track "I Want It That Way" at a recent show in Stockholm and recorded a cover of Blondie's "One Way or Another" to benefit a charity event.
One Direction is currently in the midst of an international tour, making a stop in Las Vegas next week to perform at the Billboard Music Awards.
