Would You Buy a Pair of Justin Bieber's Used Underwear? Shawn Mendes Would

Shawn Mendes recently joined host James Corden for a round of "Carpool Karaoke" on The Late Late Show.

In the segment, we learned tons of interesting factoids about the 19-year-old singer. He has his own place now, but his mother still comes over to do his laundry even though he doesn’t ask her to. He’s a hardcore Harry Potter fan. And most surprisingly, he would be willing to pay up to $500 for a pair of Justin Bieber's used underwear.  

"You know Justin Bieber just wears a new pair of underpants every day," Corden told the singer. "I think he then sells them online...it's a complete 360. Everybody's happy."

"I'd buy them," Mendes, a known fan of the fellow Canadian heartthrob, replied. "I'd probably cap it at, like, $500. Which is still a lot of money."

At which point Corden asked, "How much would you pay for a pair of my underpants?"

"I wouldn't," Mendes answered immediately. "I'd pay not to have a pair of your underpants. I would pay for them to be as far away from me as possible. Over $500."
