Cast your votes for your favorite male & female celebrities in's First Annual "Celebrity March Madness" showdown! In the spirit of the NCAA Men's and Women's Basketball Tournaments, we bring you two celebrity tournaments throughout the month of March that will determine the number one male and female celebrity - chosen by YOU!

All you have to do is cast your vote in the poll under the picture for one of the two celebs in each matchup! At the end of the round, we'll tally the votes and get the next round underway. There's even a bracket (updated after each round) with all the match-ups that you can print out (link below) and use to play along with your friends, create an office pool, or just keep track of all your own picks.

For the next two weeks we'll bring you six rounds of celebrity match-ups to vote on, much in the same style that the NCAA does: First & Second round, Sweet 16, Elite Eight, Final Four and the final Championship round to determine YOUR pick for the number one Female and Male celebrities!

The Matchup

Voting has ended for this round.

Leonardo DiCaprio is one of today's hottest actors and it seems everything he touches turns to gold. He recently starred with Russell Crowe in Body of Lies. Seth Rogen has become a big star in his own right, thanks to his "every-guy" demeanor. You probably first saw him in The 40-Year-Old Virgin, which led to roles in such films as Knocked Up and Kevin Smith's most recent film, Zack & Miri Make a Porno; which is known as just "Zack & Miri" if you get it at Walmart. Ironically, the tagline on the box art for the retailers who don't have a problem with the "Make A Porno" part on the cover is "What Would You Do To Get Out Of Debt?"; and the tagline on Walmart's version is "This Is The Last Job They Can Afford To Blow". Touche.
