BTS has been everywhere in 2019 so it's only natural that they stop by Stephen Colbert's Late Show during the thick of their US stadium tour. And being the guy Stephen Colbert is, there's no way he wasn't going to have fun with a live performance of theirs. With a very classy touch and nod to The Beatles and Ed Sullivan, Colbert introduced the K-Pop group in black and white, emulating an iconic performance. Check out the video below to see another great rendition of BTS's latest hit 'Boy With Luv'.
