James Corden turned The Late Late Show in the US into appointment-to-view television, landing headline-grabbing interviews and producing viral skits.
But now he has revealed this will be his final year at the helm of the late night chat show, deciding the time is right to move on.
Here are some of the biggest moments from the show – from singing with the First Lady to delivering powerful messages to the UK after terror attacks.
Prince Harry interview
Not long after moving out to Los Angeles, Prince Harry was interviewed by Corden on his show.
Picking him up in a double decker bus, Corden chatted to the duke, discussing his exit from the Royal Family, revealing, among other things, what the Queen bought his son Archie for Christmas.

This is burned into the minds of everyone who has seen it – but its definitely worthy of a place on this list.
Late last year, Amazon’s widely criticised Cinderella remake was released, starring (of course) James Corden.
He joined his fellow stars, including Billy Porter and Camilla Cabello, outside the studio for a Crosswalk the Musical skit – where he dressed as a mouse, thrusting his crotch at a nearby car to Let’s Get Loud.
Michelle Obama’s Carpool Karaoke
James Corden struck up an unlikely friendship with the former first lady, and did a number of projects with her as host of The Late Late Show.
But most memorably, he picked her up from the White House for one of his legendary Carpool Karaoke skits.
The pair drove around the grounds of 1600 Pennsylvania Avenue belting out hits from Beyonce and Stevie Wonder – with a surprise appearance from rapper Missy Elliot.
Corden’s friendship with One Direction
Once the world’s biggest boyband, One Direction were always highly-anticipated guests on Corden’s show.
Probably good to point out he directed the video for the group’s song Best Song Ever.
They took part in a (rather squashed) Carpool Karaoke six years ago, followed by other appearances on the show where they played tattoo roulette and even dodgeball.
After their split, Harry Styles stepped in to host the show while Corden was off in 2019.
A sort-of Carpool Karaoke with Kanye West
More Carpool Karaoke (which has actually been made into a standalone TV show), but this time 35,000 feet in the air.
After not being able to get Ye into his car for his musical commute, the pair came to an arrangement – Corden would travel on West’s jet with the rest of his Sunday Service group.
As well as joining in on some of Ye’s hits, Corden also interviewed the rapper on his fame, and then-marriage to Kim Kardashian.
Spill Your Guts with Kim Kardashian
Spill Your Guts, where stars had to tell a truth or eat some gross food, later became a controversial segment, with allegations some of the punishments were racist (for example, guests being forced to eat Asian delicacies labelled as nasty food).
Kim Kardashian is probably the most notable star to take on the challenge, revealing her least favourite Kardashian (Kylie) and which of the family is least fashionable (Khloe).
She got tongues wagging though when she drank a sardine smoothie to avoid revealing if any of her sister’s were pregnant.
The bit must have left a good impression – the Kardashian’s new programme is executive produced by the same team which makes The Late Late Show.
Message to London and Manchester
Among the celebrity moments, there were some more poignant ones, with Corden twice having to deliver emotional speeches to his home country after terror attacks.
In 2017, Corden delivered a brief monologue after the terror attack in London, telling his LA audience: “Watching the news today, I felt a really long, long way from home.
“When something like that happens in your hometown, you don’t have a feeling of being glad that you’re so far away, what you feel is that you wish you could be there with loved ones to stand alongside them.”
That was only a month after the Manchester Arena attack at the Ariana Grande concert.
Filming his message in an empty, dark studio, he said Manchester was a “strong, proud, caring people with community at its core.
“And if it’s even possible, the spirit of the people of Manchester will grow even stronger this evening. We’ll all go to bed holding our little ones even tighter this evening.”
