Some Carpool Karaoke fans have been rather unsettled by footage which suggests James Corden isn't always driving the car he's seen in within the videos.
It comes as one Twitter user shared a video of the Late Late Show host alongside Justin Bieber as the car was towed along the street in Los Angeles by another vehicle with a camera mounted on the front.
"Saw James Corden and Justin Bieber filming carpool karaoke and this is why I have trust issues — he isn't even driving!" the user, @ZoliHonig, wrote.
They went on to joke: "Next thing you know they gonna tell us that his friends don't *actually* need a ride."
Many couldn't believe what they were seeing and were quick to make the joke that it would perhaps be more apt if it were called "car-pull karaoke".
Although, others said they had seen Corden driving around filming without being pulled along.
Plus, former guest Jane Krakowski claimed when she took part in a special Broadway edition of the show in New York Corden was actually in control of the wheel, so the evidence isn't entirely conclusive.
Corden and Bieber were busy on Wednesday being filmed serving up cheese and fish tacos from the "Yummy Food Truck" with proceeds going to an LA food bank, reports TMZ.
Photographs from the news outlet showed the menu had punned on some of Bieber's hits as they flogged "Despatacos" and "Where Are You Now That I Cheese You?", putting a spin on Despacito and Where Are You Now (That I Need You), respectively.
