BTS get the star treatment they deserve in the latest behind-the-scenes episode shared on their YouTube page.

In a 36-minute video posted on Tuesday (July 31), the superstar South Korean act chronicles their 2018 Billboard Music Awards adventure, which includes a handful of guest appearances from American celebrities, including The Chainsmokers, DJ Khaled and, yes, even Taylor Swift.

While backstage at the event, where BTS performed on May 20, Swift comes into the group's dressing room for a quick photo, gushing about their ongoing success and calling them "completely different than anything" else she's ever witnessed. (High praise coming from a pop star of her global stature!)

In another cute moment, the boys hang out with John Legend, signing an album for his daughter—who Legend says is a "huge fan"—as well as teaching the crooner how to make "finger hearts."

Meanwhile, another exciting celebrity run-in indicates that a collaboration could be in the works as early as August, when BTS comes back to the U.S. for their North American tour leg: In the video, Pharrell asks the group when they can "carve some time" to work with him in the studio, to which RM replies they'll "make time" when they return on tour.
