One of Adele's most popular songs is a secret tribute to her close pal James Corden

Adele has revealed that one of her biggest hits has a secret tribute to James Corden.

The two Londoners are great friends, and the popstar recently hopped into the driver's seat for the final ever 'Carpool Karaoke'.

During the emotional ride along, Adele opened up to Corden about some of the hardships she's gone through in recent times.

In March 2021, she finalised her divorce with Simon Konecki, two years after they broke up.

Looking back at that time, Adele said she went on holiday with Corden and his wife, Julia Carey, and their three kids and her son.

And on the way home, she and the Gavin and Stacey creator had an emotional chat.

Tearing up, Adele said: "We were on our way home [from the holiday] and my mood had changed and it was like the first year that I felt like I had to hold myself accountable, for just being an adult.

"Whereas the year before that, I left Simon, you and Jules and the kids were so integral in looking after me and Angelo.

"You used to do it with humour as well, you used to be like, 'Good luck with that one!' with any sort of thing that I was pursuing, and you were always so, you were like an adult with me, you and Julia would always give me this advice.

"I remember I said to you on the way home, 'What's wrong?' you just seemed down, and you laid it all out to me, you didn't feel strong, and we had a six-hour conversation about it all the way home."

Corden admitted that he was going through a difficult time professionally.

"It was work stuff, and the Internet, and all those things," he said.

And their open conversation inspired Adele to pen some heartfelt lyrics, which would go on to form part of her hit song 'I Drink Wine'.

"It got me thinking, I felt so unsafe with you feeling unsafe, because you've always been like [the adult] you have, since I was like 21," she explained.

"I went to the studio a couple of weeks later, I wrote [I Drink Wine] and I sang it into my phone and sent it to you, and I remember you said 'that's exactly how I was feeling.'"

Corden said it was a 'privilege' to have such a beautiful song in part dedicated to him.

"It was everything I was feeling that day, I was floored by how you'd managed to take everything that I was feeling about myself and life and put it in a verse," he said.

"It is the greatest privilege, from a conversation so honest between friends, that you would create such a thing."
