It was really only a matter of time before the queen of teen pop herself joined the ranks of Carpool Karaoke stars. Naturally, all of our favourite Britney hits were covered, and James Corden even joined Britney in dressing up in that schoolgirl costume from Baby One More Time. We just can't explain how good it is. You need to watch.
When you've had George Clooney, One Direction, and Justin Bieber on your show, where do you go next? Who is famous enough, amazing enough, that you can top some of the world's most famous faces?
That's right. The First Lady of the United States was on Carpool Karoke. And it was literally everything we could ever have dreamed of. Why are American politicians inherently so much cooler than ours? Much as we love Philip May, we really can't see him jamming to Missy Elliot. Words can't do Michelle's appearance justice. Just watch it.
If you haven't got your Carpool fix, then last week's apperance form Selena Gomez was also pretty brilliant.
James Corden and Late Late Show executive producer Ben Winston are said to be shopping out the carpool concept to TV stations - and according to reports, it's already garnering massive interest. Did someone say massive bidding war?
With special guests George Clooney and Julia Roberts...
Red Hot Chili Peppers
When James Cordon invited the Red Hot Chili Peppers into his car, their soft rock vibes took us back to the early noughties. Cordon and the gang sang their way through their impressive repertoire of the Chilli Pepper's hits that you'll definitely remember the words to, including “Can’t Stop,” “Californication,” “The Zephyr Song”, getting hot and deciding to strip off, though drummer Chad Smith and guitarist Josh Klinghoffer did remain fully clothed throughout. Not content to keep their antics to the car, at one point, Corden pulled over so he and frontman Anthony Kiedis could partake in some manly wrestling on a lawn.
