However, it has been revealed that the One Direction star and DJ decided ruthlessly cut James' appearance.
Corden's harrowing ordeal was captured on video and played to The Late Late Show audience.
James shows up late to the recording and discovers that Steve had laid down Louis' vocals and the pair were happy with it - on its own.
"We're really proud it," Louis tells a despondent James.
Corden's further suggestions didn't do anything for the 1D star or DJ so they let James think he could record his vocals while leaving the studio.
Obviously this was just a short sketch for James's The Late Late Show which ten sees him team up with celebrities to create fabricated drama.
In the past James has "auditioned" for TV show Empire alongside Taraj P. Henson for the role Cookie, as well as appear in an underwear ad with David Beckham.
It's not the first time Louis has taken part in dome Late Late Show fun as he and One Direction took part in Tattoo Roulette.
