A video of James Corden and Justin Bieber filming a Carpool Karaoke segment went viral last week. The footage showed that Corden wasn’t driving at all. He and Bieber were being pulled on a truck.

The revelation sent “shockwaves” through social media. Corden addressed the video on Wednesday’s Late Late Show. He said, “I know this looks bad, but I just want to say right now that I always drive the car unless we’re doing something where we think it might not be safe. Like a dance routine, or a costume change or if I’m drunk.
