Grab your corsages and boutonnieres: Prom season is officially upon us, which means it's time for us to begin the hunt to determine this year's official Prom King and Queen of 2016.

Last year, after weeks of voting, Harry Styles and Ariana Grande took their respective crowns. And since they've gone on and graduated, it's time for the next wave of teen pop sensations to vie for the title.

In this first round, it's Fifth Harmony's Lauren Jauregui versus Disney pop princess Laura Marano — both of which have been making waves lately with their individual projects.

Along with her solid vocal offerings in 5H, Jauregui's kept the Harmonizers' heartrates steadily above normal with her hot-as-fire photo shoots, and most recently possibly-maybe tried to kill as all with her Kode Magazine spread.

Marano, on the other hand, has got her fans' hearts pounding to the sound of her latest single "Boombox," which she's been promoting in between working on Disney's Austin & Ally.

They're both two promising talents in their own right, but only one can move on to take the crown in our competition. So who will it be?

Vote now below — this round ends Sunday (May 22) at midnight.
