Justin Bieber just stole the show -- literally!

The pop singer hijacked last night's Late Late Show with James Corden and it was pretty damn funny! The 21-year-old took to the stage for the late night show's opening monologue, which is usually performed by the cheery Brit.

The Biebs started the monologue with a few timely jokes like, "I read that Jeb Bush's super PAC has spent over $15 million on his campaign, meanwhile Bernie Sanders has spent over $5 on his latest haircut."

Soon after Corden came by in a bathroom and towel on his head and interrupted Bieber's time in the spotlight. The two bantered until Corden decided to keep JB hosting the show for the the night. Hurray!

Before the show, the "Sorry" singer Instagramed a dapper pic of himself, which showed off his new (and 52nd!) tattoo, which is located on his neck and is of wings.

Selena Gomez's on-again/off-again ex shared a photo which showed him standing in front of a vanity mirror, wearing a black tuxedo and white shirt. The pic, which was taken by someone standing behind him, said, "New tattoo :)."

We think this tattoo is pretty damn dumb!
