Demi Lovato was able to beat out Selena Gomez in the first round of Prom Queen voting, and Miley Cyrus was also able to nudge out her competition, Taylor Swift, to advance to Round 2. Now, the 'Heart Attack' songstress and the 'Ashtrays and Heartbreaks' hit maker will go up against each other in our fan-voted battle for PopCrush's Prom Queen of 2013!

While Demi Lovato and Miley Cyrus have a lot in common, they are also extremely different, which may make your choice for Prom Queen easier or harder, depending on how you look at things.

Let's start with the similarities, like the fact that both are former Disney starlets who have morphed into serious pop divas with chart-topping records. Outside of music, they both care deeply about humanitarian efforts, whether it's helping out animals or struggling teens. Finally, they also both have that edginess going on physically, with their tattoos, love for leather, and the list goes on.

But they are also very different, from the sound of their voices and music, to their public personas, as Demi has moved out of the party girl realm into a much more mature place, while Cyrus is still getting her inner wild child out while also maintaining her homebody lifestyle.

So, who gets your vote for Prom Queen this round? Miley or Demi? You can vote once per hour below until the poll closes on Friday, May 17, at 12PM ET, and the winner of this match will advance to the finals. Good luck!
