Charlie XCX's hugely catchy Boom Clap is taken from a movie that looks like being a massive hit this summer, The Fault In Our Stars, adapted from the successful young adult novel by John Green. And Sing J Lee's video seamlessly connects Charlie's performance in Amsterdam with a crucial section of the movie, when the fireworks start going off for Hazel and Augustus, the movie's main characters.

SING J LEE:

"We wanted to shoot a fun, feelgood performance promo that would sit well with fans of the forthcoming film The Fault in Our Stars.

"The song features at the pinnacle of Hazel and Gus's love for each other during their trip to Amsterdam, and we wanted to latch on to that uplifting moment."
