HALSEY "LUVS" BTS (UPDATE)

BTS has teamed up with Halsey on upcoming single "Boy With Luv"—we know that because they’ve dropped a teaser for it. The song appears on the K-pop group’s next EP, Map of the Soul: Persona, due via BigHit/Columbia on Friday, one day before their SNL performance.

#BoyWithLuvTeaser quickly shot to the #1 Trending spot on Twitter Sunday morning, while the 46-second clip (embedded below) racked up more than 2m views in a matter of a few hours.
