The K-pop boy band performed their new single with Halsey, "Boy With Luv," at the awards show at the MGM Grand Garden Arena in Las Vegas, Nevada, on Wednesday. Jimin, Jungkook, RM, J-Hope, V, Jin and Suga -- who won both awards they were nominated for, Top Social Artist and Top Duo/Group -- couldn't have looked more in sync as they sported matching black-and-white looks during the high-energy number.
Halsey, who wore a coordinating look, later appeared from the back of the stage, surprising the crowd as she joined the band in their tight, complex choreography.
It's been an eventful past few weeks for BTS, who were recently honored as one of TIME Magazine's 100 Most Influential People. Halsey wrote a sweet tribute to the band, explaining why they've become so beloved around the world.
"I have known 'the boys' -- as I and other fans affectionately call them -- for years and had the pleasure of traveling to Korea to hang with them on multiple occasions," she wrote. "Outwardly, they are polished and professional, but hours of laughter, secret handshakes and gifts exchanged show those around them that underneath this showstopping, neatly groomed movement are just some guys who love music, one another and their fans."
"For BTS, world domination is just another 8-count in the contemporary dance of life," she added. "But if you think that’s easy, you haven’t seen the love and effort these young men put into each and every step."
