"Thanks for making tonight Larger Than Life @j_corden! #Jamesstreet #BSBVegas," read a message posted on the boy band's Instagram page, alongside a video of Corden performing onstage.
It is unclear whether Corden's cameo was recorded for a segment on his talk show, where he often takes part in musical sketches, most famous being Carpool Karaoke.
Corden had also performed with the Backstreet Boys in 2016, on The Late Late Show.
He surprised his audience by introducing them onstage and then joined them in a performance of "Everybody (Backstreet's Back)."
