And then there were two.

After weeks of voting, the competition for PopCrush's annual Prom King of 2016 has come to its thrilling conclusion, with 5 Seconds of Summer's Michael Clifford vying against "Stitches" superstar Shawn Mendes for this year's crown.

Last week, Michael Clifford successfully beat out his own bandmate Luke Hemmings in a #5SOSFAM showdown, winning with over 53% of the vote. And, at the same time, Shawn Mendes proved victorious in his own battle with Jaden Smith, moving forward with just over 52% of the vote.

And now, it's time to decide. Which pop star will ultimately reign supreme on this year's PopCrush prom court — Shawn or Michael?

Place your vote below. The voting period starts now and ends on June 6 (Sunday night) at midnight.

And while you're at it, make sure to vote for this year's Prom Queen: Will it be Lauren Jauregui or Chloe Grace Moretz?
