James Corden joined 90s pop group, The Backstreet Boys, on stage at the Las Vegas residency.

Corden replaced band member Brian for their opening number 'Larger Than Life'.

In a comedic video filmed for Saturday Night Life, Corden insisted on joining the band, offered a "break" for one of the group's members.

The talk-show host learned a tough choreographed routine and dazzled fans by appearing on stage during the elaborate entrance song.

Corden's stint in the band wasn't for very long though, with Brian coming on stage before the number was finished. Corden thanked the crowd and left the stage.
