After a few weeks of heated competition, we've finally arrived at the final round of voting for PopCrush's Prom King and Queen 2013! So, which of our finalists will be crowned the ultimate prom champs by all of you readers?

The list of potential crown winners has been narrowed down from 32 all the way to four finalists, with Justin Bieber and Austin Mahone left in the King category, and Demi Lovato competing against Perrie Edwards of Little Mix in the Queen category. It was a tough race to these rounds, as the four finalists had to beat out names like Chris Brown, Harry Styles of One Direction, Miley Cyrus and Selena Gomez.

As we said before, on the male side of the spectrum, we've got 'As Long as You Love Me' heartthrob Justin Bieber and 'Say You're Just a Friend' cutie Austin Mahone duking it out for the title of PopCrush Prom King of 2013. With their super good looks, heart-melting smiles, suave personas, swaggy fashion senses, and of course, awesome music, either of these teen superstars would make a great Prom King in PopCrush's fan-voted poll.

Meanwhile, 'Heart Attack' hit maker Demi Lovato and 'How Ya Doin'' songstress Perrie Edwards are going head-to-head for PopCrush's 2013 Prom Queen tiara. Lovato is an inspiration to all, with her compelling life story and empowering messages via song, and of course, is a stunning, charming young lady with tons of talent and personality. The same goes can be said Edwards, though. The Brit rose to fame practically overnight, and she's adorable, sweet, sassy and colorful, both with her wardrobe and bubbly demeanor.
