They say “Snitches get stitches,” but what if the snitch is RM? The BTS leader is known for being an honest person, but sometimes he gets too honest for the entertainment industry. And even though he has a genius-level IQ, he gets pretty clueless at times, not knowing when to bite his tongue.

RM has a history of spoiling things such as BTS’s comebacks, tours, and more. These events are super top secret, but the BTS leader just usually talks about them as if they weren’t a big deal, giving the rest of the members a mini heart attack.

Now, RM recently proved that his spoiler king status is not only limited to BTS. The 25-year-old rapper, songwriter, and record producer also snitched on James Corden and shared a little-known fact about "Carpool Karaoke."

On January 29, BTS guested on The Late Late Show With James Corden. They performed their song “Black Swan” for the very first time since the release, and they even played hide and seek with the host and Ashton Kutcher.

After almost a month later, the much-awaited BTS “Carpool Karaoke” is finally airing. The concept for the segment is quite simple. James Corden and his guests would sing along to songs while the host drives them around — or so it seems.

RM revealed in a new interview with Entertainment Tonight that James Corden wasn’t driving the vehicle in “Carpool Karaoke.”

“[The filming] took like three, four hours,” RM said. “I heard it’s the biggest car they ever rented because we’re seven. Some van, like really hot inside…Like, 16 cameras inside, and Corden was not really driving it. I didn’t know, I thought he really drove, but safety first.”

RM just exposed to everyone that James Corden had been pretending to drive all these years. And of course, ARMYs are having a field day with this information.

“Namjoon exposed James Corden for not driving the car! Not this gets more and more interesting,” one wrote. “Lmaoooo namjoon just exposed James Corden acting out and not really driving HAHAHAHAHAHAHAHAHA,” another one shared.

But James Corden not driving in the “Carpool Karaoke” segment is nothing new to those who see the host shooting the episodes. Because even though James Corden is not driving, the car really does go around in certain areas where it is spotted by a lot of people.
