It's been five years since Justin Bieber made his Carpool Karaoke debut, but now he's back for second helpings.

The Canadian star, who has just released his new album 'Changes', hopped into the passenger seat beside James Corden for another trip down memory lane.

This time, Bieber teaches Corden the dance moves to 'Yummy' and grills him on some tough questions about his past choices and his marriage to Hailey Baldwin/Bieber.

He also asks him about that time last year when he challenged Tom Cruise to a fight. Yeah, that one.

Of course, there's a few tunes in the mix, too - like his duet with Ed Sheeran on 'I Don't Care', 'Love Yourself', 'I'll Show You' and even 'Smelly Cat' from 'Friends'.
