James Corden is officially leaving The Late Late Show, Hollywood, and American stardom behind. The talk show host, former British national treasure (back when he was reliable ol’ Smithy from Gavin and Stacey), and somewhat questionable musical performer is hanging up his prime TV spot and heading back to the UK.

And who did he choose to send him off? None other than present day superstar and overall sweetheart, Adele. The pair filmed one final version of Corden’s flagship segment Carpool Karaoke and during the process, both celebrities revealed some details about their struggles and seemingly intimate and close friendship.

The 21-minute video kicked off with Adele sneaking into Corden’s bedroom and waking him up with a seriously impressive pair of cymbals. The duo then got into a car and began making their way to the filming studio.

Naturally, the video contained a lot of the classic Carpool Karaoke bits and bobs, lots of singing of Adele’s classic hits and some general chit-chat and banter. But what made this particular episode so interesting, is the fact that Adele and Corden chose to open up about some very personal moments between the two. In fact, their friendship was so palpable and heartwarming it even got me rethinking my opinions on the comedian. That’s the power of Adele.

At one point, the Grammy-awarded artist recalled a story in which herself and Corden shared a six-hour long conversation as they travelled home from a holiday together with their families. The ‘Someone Like You’ singer shared how Corden and his wife Julia played an integral role in helping look after her and her son Angelo.

Moreover, after hearing how Corden himself was also struggling in his life, Adele wrote the first verse of ‘I Drink Wine’ in tribute to him. The TV host got quite emotional as he noted: “I was floored by how you’d managed to take everything that I was feeling about myself and life and just put it in a verse. It was the greatest privilege from a conversation so honest between two friends. That you could create such a thing, it just blows my mind.”

To refresh all of our memories, the first verse of Adele’s hit ‘I Drink Wine’ goes: “How can one become so bounded by choices that somebody else makes? How come we’ve both become a version of a person we don’t even like?”

The duo both got incredibly sentimental during the car journey. In an interview with Variety, Corden explained: “What you’re actually watching is two friends who moved to Los Angeles, I think a week apart. And one of them is going home and one of them is staying. That’s hugely emotional. It just so happens that one of them is the biggest singer in the world.”
