Cast your votes for your favorite male & female celebrities in Starpulse.com'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 match-up! 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!

George recently starred in Burn After Reading alongside pal Brad Pitt, and is a crusader for peace in the Darfur region of Suday; and Jack warmed our hearts as the lovable Po in Kung Fu Panda. Skidoosh!

Who's it gonna be? George or Jack? Vote!

The schedule:
First Round Voting: March 19-22
Second Round Voting: March 23-25
Sweet 16 Voting: March 26-28
