It's nearing the end of the school year, and some of you might even be done already, but in order to extend the fun of yearbook superlatives into the world of celebrities, we're taking fan votes for some of pop's hottest stars in a variety of categories. So, who will take the titles of Best Smile, Class Clown plus many more end-of-school superlatives? It's up to you, the readers, to decide!

The PopCrush staff has broken it down to 10 superlative categories, with a number of stars nominated in each. But unlike most yearbooks, we're heating up the competition by placing men and women against one another in order to crown the ultimate winner in each category -- like they say in 'Highlander,' "There can be only one!"

Here's the category rundown for PopCrush's 2013 Celebrity Yearbook Superlatives competition: Best Smile, Best Hair, Best Eyes, Best Dressed, Class Clown, Cutest Couple, Most Athletic, Best Nickname, Most Likely to Succeed and Most Inspirational.

With names like Adam Lambert, Beyonce, Chris Brown, Demi Lovato, Justin Bieber, Miley Cyrus, Selena Gomez and Taylor Swift in the running in a number of these fan-voted polls, the competition is sure to get heated! Click through below to start voting in all 10 categories, and remember that you can vote once per hour until all of the polls close on Friday, June 21 at 12PM ET. Happy almost summer, and happy voting, PopCrushers!
