There can be only one King on the Prom Court — and we're about to seriously shake up the 5SOSFAM. (Sorry in advance.)

It's the second round of this year's annual Prom King and Queen competition, where Young Hollywood's finest go head-to-head for the crown.

In the first round of the competition, 5 Seconds Of Summer star Michael Clifford successfully beat out Brooklyn Beckham with a whopping 65% of the vote. And, at the same time, 5SOS's Luke Hemmings came through just narrowly beating Dylan Sprayberry with 50.3% of the vote.

And now, it seems, we've officially got a 5SOS showdown in Round 2. Which one will take the crown — Michael or Luke? The competition will close at midnight on May 30 (Sunday night), so get your votes in now. Go, go, go!
