“Watch Justin Bieber Do The Opening Monologue On ‘The Late Late Show With James Corden’

What Ellen DeGeneres is to Justin Bieber for daytime talk show hosts, James Corden is becoming something similar in the realm of late night hosts: an ally. The Late Late Show host was one of the first to embrace Bieber's image rehabilitation tour, when they collaborated on one of Corden's now signature Carpool Karaoke bits. Their growing bond was once again evident on Thursday, when a playful Bieber crashed Corden's set and stole his opening monologue duties. Of course, Corden was having none of it, and stormed onto the stage in a bathrobe and a towel wrapped around his head. Eventually though, the two patched things up, and Bieber was allowed to finish the monologue. After all, what are friends for? Watch above.
