Welcome to the championships! We've got two gals and two dudes left, fighting to be the Hottest Male and Female Star of 2013!

We started with 16 hot pop stars, then we had eight, and now we are down to four! For the males, we have the swaggalicious Justin Bieber up against shirtless hunk James Maslow of Big Time Rush. For the gals, 'Made in the USA' startlet and 'X Factor' judge Demi Lovato is duking it out with ‘Applause’ songstress Lady Gaga.

Whoever wins the championship round will go on to win the title of the Hottest Male Star and Hottest Female Star of 2013! Remember, YOU decide who is deserving of these titles, PopCrushers.

So, who will reign supreme? Voting for the championship round will run until Sept. 30 at 2PM ET. We will announce the winners shortly after. Good luck!
