This might be the most honest Carpool Karaoke yet! Jason Derulo joins James Corden for a Carpool Karaoke session and reveals he's had four girls in his bed at one time.
And talking of beds, Jason Derulo tells James that he's got a round one, to which James asks: "Where do you buy sheets for a round bed??"
The video sees the pair travelling around Los Angeles singing some of his hit songs before Jason gives James a dance tutorial and the two take over a star tour.
