James Corden got Will Smith in the car to help him unveil the premiere episode of Carpool Karaoke: The Series.
As the first guest of honour, Will kicked things off with 'Gettin Jiggy Wit It' before taking on 'Boom! Shake the Room'.
He also revealed that he wrote his first rhyme when he was just 12 years old, also telling James that he released his first record at the age of 16 – some 30 days before high school ended...
To which James quipped: "In your yearbook, were you voted Most Likely to Have Already Succeeded?"
You can watch the first six minutes of the premiere episode of Carpool Karaoke: The Series right here, but to watch the whole episode, you have to be signed up for Apple Music.
Last week, James finally got his revenge on Gordon Ramsay. Gordon made James eat a fish eye on The F Word seven years ago, which was meant to be in exchange for a meal at one of Gordon's restaurants for James's entire family.
However, as James's dad reminded him, Gordon never made good on his promise, so James figured it was time for revenge, and served him up a fish eye to eat.
Despite Gordon seeming to take the punishment in his stride, it didn't take long for him to vomit it back out and all over the set of The Late Late Show.
