The K-pop sensations will kick off the special on Monday 28, 2020, and perform hit tracks like their recent hit Dynamite.
Members RM, Jin, Suga, J-Hope, Jimin, V, and Jungkook will also take part in comedy shits and a virtual interview with host Fallon.
“I’m so excited to have BTS back on the show. We just started the new season and we’re working on a lot of really exciting things,” Fallon told Entertainment Weekly in a statement. “One thing that is important to us at The Tonight Show is showcasing talent and creatives, so what better way to kick things off than a full week with them. And this is just the start.”
