The rapper has long been linked with an appearance on The Late Late Show's popular Carpool Karaoke, with Corden previously revealing West had cancelled three times.
He finally made an appearance of sorts during Monday's episode.
However, in a twist befitting an artist with the grandiose pretensions of West, he and Corden ditched the usual 4x4 and instead took to the skies in a jet packed with the musician's Sunday Service choir.
During the flight West, who has just released his latest studio album, Jesus Is King, opened up on family, religion and his struggles with mental health.
Speaking about his five-year marriage to reality TV star Kim Kardashian, West explained: "Marriage years are different than human years.
"Like you know how dog years are like seven years? Every marriage year is like 100 years."
West joked it felt as though he had been married for "500 years". West, a father of four, said during his darkest moments his loved ones struggled to help him.
"People in my family were praying for me, but they couldn't call me and scream at me. I'm a grown man," he said.
"But it was God that came and put this thing on my heart and asked if I was ready to be in service to him."
West added: "I have no regret and no shame."
West, 42, was joined by his choir for a performance of one his biggest hits, Jesus Walks.
They finished the segment with a rendition of Selah, a song from Jesus Is King.
