Backstage at the 2018 Billboard Music Awards, BTS sparked a question that ignited a fire, and tons of other artists hopped on board. The K-pop stars set it off by asking the Backstreet Boys to share the secret to their lasting success. BSB answered the question and fired a few off for Echosmith, who answered before passing the baton off to Bebe Rexha. Closing out the chain was Dua Lipa, who answered Rexha's question.
