We decided to make this week's Pop Wars Justin Bieber-themed, because why not, ya know? But are Cat and Meghan as much of Beliebers as we are? We put the ladies to the ultimate Bieber battle and tested their Bieber trivia, and whoever gets more Bieber Bux at the end wins! So watch above, and don't forget to play along and tell us which q's you got wrong (or right) in the comments below.
Congrats to the winners of last's week giveaways! Vampire Diaries tote SinlyxBlackxRoses
