Adele and James Corden reunited for the last  segment, and it was a wondrously touching final drive.In the 21-minute long video, the «Someone Like You» songstress surprises the  host in his home before the duo buckles up and takes a drive down memory lane, reminiscing on previous guests like Mariah Carey and Stevie Wonder, and giving viewers an intimate peek inside their close friendship.Adele reveals that Corden and his wife, Julia, have been her two greatest confidantes for years, especially after she relocated to Los Angeles after her split from Simon Konecki, the father of her son, Angelo.

The singer explains that a conversation between her and Corden inspired the song «I Drink Wine,» which she boasts has some of her «best writing.»   «We'd been on vacation together with the kids and we were on our way home and my mood had changed.

And it was the first year that I felt like I had to hold myself accountable for being an adult whereas the year before that, I had just left Simon and stuff like that,» she recalls. «But you and Jules and the kids were so integral to looking after me and Angelo, and you used to do it with such humor as well.

You were always so an adult to me, and you've always given me advice.»The singer shares that the duo had an almost six-hour conversation as they poured their hearts out to one another and the conversation became the first verse of her song that she later performed for Corden over the phone.«It was everything that I was feeling that day.
