Jay-Z, Snooki, Jon Hamm And More: Find Out The Stars' Favorite Baseball Teams!

The post-season is approaching fast, and we know who the biggest celebs are rooting for.

The MLB postseason begins in just three weeks, and a slew of famous sports fans can't wait to be taken out to the ball game.

That's right: Celebs ranging from Jay-Z to Jon Hamm will be watching the action on television just like us -- or sitting in the stands (likely behind home plate, because stardom comes with serious perks). But don't expect to find them all under the same stadium roof, as not every star cheers for the same team, of course.

So who's rooting for who? Check out our list of celebrity fans to find out, and be sure to get your baseball fix with "Off the Bat from the MLB Fan Cave" every Sunday at 11/10c on MTV2:

Jay-Z

No surprise here. The man behind "Empire State of Mind" is a die-hard New York Yankees fan, which most of you may or may not have figured out from Hov's signature hat.

Snooki also roots for a New York team, but it's not the Bronx Bombers. Here she is on a date night with her then-boyfriend (and now fiancé) Jionni at the New York Mets' Home Opener in 2011 -- long before Lorenzo and a bun in the oven kept her busy!

Ashton Kutcher and Mila Kunis

Another guy who takes his lady out to the ball game is Ashton Kutcher. Take a glimpse of the daddy-to-be and his better half Mila Kunis cozying up together at an LA Dodgers game this past summer.

Boston native Ben Affleck is a Red Sox fan through and through -- and perhaps one of the biggest. Fun fact: When he directed the 2010 movie, "The Town," Ben chose to shoot one of the film's pivotal scenes at Fenway Park!

This "Mad Men" star's allegiance to baseball follows him to the big screen. Earlier this year, Hamm played a sports agent in "Million Dollar Arm," and "Off the Bat"'s Melanie Iglesias even chatted with him about it recently. IRL, Jon is a St. Louis Cardinals fan.
