Two 17-year-old heartthrobs. One crown.

PopCrush's annual Prom King and Queen competition continues onto its second round today, as Young Hollywood's finest go head-to-head into a battle to determine who rules the court this year.

The battle started off with a bang, as the effortlessly stylish Jaden Smith successfully trumped R5 star Ross Lynch with over 54.7% of the vote. At the same time, Vine sensation-turned-pop superstar Shawn Mendes claimed victory over his fellow Vine pal Cameron Dallas with a strong lead of over 61% of the vote.

Both boys have fervent fanbases, but only one will move on to the final round to claim a spot on this year's throne. Who will it be? The competition will close at midnight on May 30 (Sunday night), so get your votes in now. Go, go, go!
