We all sing in the car sometimes, but it's hard to imagine famous musicians doing it to their own music.
But now we can. Fresh new host of 'The Late Late Show', our very own James Corden, tricked Mariah Carey into singing along with him while driving around Los Angeles.
Their carpool karaoke was secretly filmed and included classic tracks like 'Always Be My Baby' and 'Fantasy'.
It wasn't long before romance started to bloom between the two, and Corden is actually a pretty decent singer. Who knew?
