If only we could all live as decadent a lifestyle as Justin Bieber. The pop star revealed on Wednesday’s Late Late Show with James Corden that he only wears pairs of underwear once—but there’s a catch.

For his Carpool Karaoke segment, host James Corden drove Bieber around L.A. and asked the singer about participating in Calvin Klein underwear advertisements. “They send me a lot of Calvin Kleins, like boxes and boxes,” Bieber explained, leading Corden to quip, “So do you just wear ’em once and throw ’em out?”

“Yeah, I definitely don’t wear them twice,” Bieber answered to a disbelieveing Corden. “There’s so many!”

“That’s the life,” Corden said. “I have to turn mine inside out and wear them again.”
