This is what we call a Justin Bieber problem.

On Wednesday night, Bieber, 21, appeared on CBS's "Late Late Show with James Corden" and revealed that he only wears underwear once.

Well, sort of. Let me clarify.

Corden, 36, drove Bieber around Los Angeles and asked him about his Calvin Klein underwear ads.

In response, Bieber said, "Yeah, I definitely don't wear them twice. There's so many!"

I mean, I wish I had that problem, Biebs.
