- Shawn Mendes participated in a new "Carpool Karaoke" segment on Monday as part of a week-long takeover of CBS' "The Late Late Show With James Corden."
- While driving with Corden, the singer revealed that he would pay no more than $500 for a pair of Justin Bieber's used underwear.
- Mendes said he would especially consider buying a pair if Bieber played hockey in them, or did another cool activity.
- The conversation was sparked by Mendes explaining that he recently moved into his own home, but his mom still does his laundry.
- Corden then told Mendes that Bieber"wears a new pair of underpants every day" and "sells them online."
- Watch the video below (Mendes talks about buying Bieber's used underwear at 1:15).
