PopCrushers, we've got a challenge for you! As the temperatures rise this summer, we're on a quest to determine the Hottest Star of 2014! In Round 1, we have Jason Derulo facing off against Macklemore. Who should advance to the next round?

There's no doubt that Jason Derulo has been steaming up the pop music scene as of late. His infectious hit 'Talk Dirty' took over radio waves, while his newest track 'Wiggle' celebrates a woman's, err, assets. Of course, Jason is also a total sweetheart. He positively glows when he's around his lady, Jordin Sparks, and what's hotter than a guy who is talented and lucky in love?

Macklemore has had a major year -- and he's got the hardware to prove it! He collected four, count 'em FOUR, Grammys at the awards earlier this year, including Best New Artist! With his infectious beats and empowering messages, the hip-hop artist is changing the face of music. We love that Macklemore is using his influence to take a stance on important issue and continues to inspire other artists. We're willing to bet 2014 is only going to get hotter for this star!
