It was one of the best things to happen in 2015 – Carpool Karaoke! James Corden cracked America and has had some of the biggest celebrities in his car – for singing and general lols.
Based on the premise that in America there’s a carpool system so you can’t drive in a certain lane unless there’s more than one person in the car, James Corden gets his celeb pals to hop in and have a fun drive for his Late Late Night Show.
His latest Carpool Karaoke companion was probably the coolest yet... Only the First Lady, Michelle Obama! She's singing and being generally great, WITH Missy Elliot.
And InStyle cover girl Selena Gomez sung on a rollercoaster like a BOSS...
In more CK news, Twitter has announced One Direction was the most Tweeted about Carpool Karaoke ever (... those One Directioners can't be beat!).
And, still one of our faves, 'J-Lo and J-Co' singing to her frankly excellent music and texting Leonardo DiCaprio...
And the best ever, including the Grammys special...
To kick of 2016, James got the biggest pop singer of the moment (that's not Bieber, the other one) - Adele! We <3 her so much right now...
And THEN, calling all Coldplay fans! James Corden picks up Coldplay frontman Chris Martin on his way to the Super Bowl in San Fran - and it's actually pretty lols.
And THEN - Elton John is out and about promoting his new album, and stopped in via James's car. Watch it here...
And Sia, who is actually a total babe albeit with a quirky two-tone bob...
