Justin Bieber's Carpool Karaoke Is HERE!

Justin Bieber's Carpool karaoke is here and we finally know why they took extra safety measures and towed the ride (instead of having James drive).

They were creating a TikTok dance to Justin’s new track "Yummy." Justin also challenged James to arm wrestle and won.

They also chatted about marriage and about why Justin challenged Tom Cruise to a fight last year.
