Start polishing that crown: PopCrush's yearly competition to determine our official Prom King and Queen begins now.

Last year, Harry Styles and Ariana Grande made a handsome pair as our winning Prom King and Queen team. Since they've graduated from high school, who will join the royal ranks this year?

In the first round, it's the endlessly stylish Jaden Smith versus R5 superstar Ross Lynch, and they both make compelling arguments for why they deserve to be the reigning champ this year.

Along with making a massive splash in the fashion scene for his fearless style and enviably cooler-than-cool swagger (not to mention a Twitter feed that provides daily food for thought and philosophies), Smith has been breaking out in movies and television with roles on The Get Down and the upcoming The Karate Kid 2.

Lynch, on the other hand, along with recently storming the Disney Channel screens with a starring role on Teen Beach 2Austin & Ally. He's busy doing double duty on stage, too: R5 is currently touring the country on their Sometime Last Night Tour.

So now, it's time to decide. Who moves on to the next round?
