Justin Bieber Vs. Justin Timberlake? Vote In Our Epic BATTLE OF THE JUSTINS!

Justin Bieber vs. Justin Timberlake. WHOSE SIDE ARE YOU ON?

++ UPDATE! FIND OUT WHICH JUSTIN WON OUR BATTLE OF THE JUSTINS! ++

Justin Bieber vs. Justin Timberlake: a truly epic battle that may ultimately end friendships and turn brother against brother. But screw it. LET’S DO THIS!

In celebration of Justin Bieber’s brand-new album, Believe, and Justin Timberlake, welp, being Justin Timberlake, we here at MTV Buzzworthy and MTV News thought it’d be fun to cause worldwide havoc reexamine the trajectory of both Justins and see how they stacked up against each other.

We did a side-by-side Bieber-to-Timberlake analysis of categories including but not limited to sales, social media, big-screen success and my personal fave, precociousness. We’re sort of shocked there wasn’t an “attractiveness” category, but if that did in fact exist, our vote would have to go to Timberlake simply because of how special he looked while wet and shirtless in THIS VIDEO. (A throwback, I know.) But then I think about Justin Bieber and all that swag, and I DON’T KNOW! IT’S UNFAIR! So, world, YOU decide!

Who’s the greatest Justin of all time? Justin Bieber, the CHALLENGER, or Justin Timberlake, THE CHAMPION! Vote in our poll below, and check back Friday, June 29, to see which Justin reigns supreme!
