Complete with an 80s-era Richie-inspired wig and a very retro metallic jacket, Fallon definitely looked the part as he launched into his rather impressive rendition of the track, reported Entertainment Tonight.
In a nod to the original music video, Fallon can be seen working on creating various likenesses of Richie, 66, throughout the clip, including a very realistic painting, while the hit singer himself takes the place of the infamous clay bust.
Meanwhile, Richie recently announced that he will be the latest star to take up a residency in Las Vegas.
