Sept. 11 (UPI) -- South Korean boy band BTS will release a collaboration with American duo The Chainsmokers.
Billboard confirmed Monday that Rap Monster, Suga and J-Hope co-wrote the song "Best of Me" with The Chainsmokers member Andrew Taggart for BTS' forthcoming album, Love Yourself 'Her.'
Sources described the collaboration as "an energetic dance track," with The Korea Herald adding the song features The Chainsmokers' typical "expressive harmonies."
BTS met The Chainsmokers prior to the the 2017 Billboard Music Awards in May. The Chainsmokers teased a future collaboration while sharing a photo with the boy band on Twitter ahead of the awards show.
"Love these dudes! See you guys this summer @BTS_twt," the duo wrote.
"Best of Me" marks BTS' first project with an American act. The group is steadily gaining international exposure, winning Top Social Artist at the Billboard Music Awards and making a New York Times list of the most-watched acts on YouTube in the U.S.
Love Yourself 'Her' will debut Sept. 18. The boy band teased the album by releasing a "Serendipity" comeback trailer featuring Jimin last week.
