Justin Bieber puts his mustache on the line in Spill Your Guts or Fill Your Guts

Justin Bieber finished his week on The Late Late Show with James Corden by playing a round of Spill Your Guts or Fill Your Guts.

“Spill Your Guts or Fill Your Guts” can be a double-edged sword for a celebrity like Justin Bieber. On the one hand, so much of his life has been in the public eye and there are few details that are truly secret. And on the other hand, those secrets involve some of the other biggest names in Hollywood.

For those reasons and more, the game was also the perfect way to close out Bieber’s week on The Late Late Show with James Corden. The singer already gave fans another edition of “Carpool Karaoke” as well as a “Toddlerography” segment and more.

As usually, the Late Late Show writers did not hold back in the questions posed to both Bieber and James Corden. Sure, some topics were likely deemed off-limits but that could be to maintain the solid, mutually beneficial relationship between Bieber and The Late Late Show.

Watch below as Bieber takes questions about fans around the world, his wife Hailey Baldwin’s friends, and most importantly his mustache. On the other side of the table, James Corden is put on the spot about Cats, Bieber vs. Harry Styles, and his late night competition.

No contestant on “Spill Your Guts or Fill Your Guts” is ever pleased with the options (except maybe Jimmy Kimmel) and Bieber is no different. The pop star is visibly disgusted by the “food” and has a hard time staying at the table. It is as if he’s never seen the game played, even those his close friend Kendall Jenner is a pro at it by now.

But maybe the fact Bieber isn’t all that familiar with the game was a good thing. No other guest has challenged James Corden to actually swallow. Typically, the comedian takes a bite, gags, and spits it into a bucket. Here, Bieber makes sure that Corden finishes his bite of cow tongue.

And just like Bieber didn’t want to ruin his mustache, Corden was careful not to ruin any professional relationships. He is open and honest about his experience making Cats. It’s good to see him joking about it especially since the sting from that flop won’t be leaving him anytime soon. Corden also takes the high road rather than rank fellow late night hosts like Jimmy Fallon, Jimmy Kimmel and Seth Meyers proving once again that “late night wars” no longer exist.
