The K-pop sensations, who released their new album "Map of the Soul: 7" on Friday, February 21, have already filmed their scenes for the show which airs February 25, and they told Entertainment Tonight they were surprised by the experience.
"It took like three, four hours. I heard it's the biggest car they ever rented because we're seven (members). Some van, like, really hot inside," singer RM shared. "Like, 16 cameras inside and Corden wasn't driving it. I didn't know, I thought he really drove, but safety first."
Although James Corden usually drives, he's previously explained that he doesn't drive the vehicles if the team thinks it might not be safe, due to various production elements.
The "Boy With Luv" group also confessed they were excited to share new music with fans, and confessed the new record gives a glimpse into "what's inside our souls".
BTS is also going to be embarking on a "Map of the Soul Tour", which kicks off in April.
