Happy Opening Day, baseball fans! Finally, after five long months (maybe more, if your team didn't make it to last year's post-season), America's favorite pastime is back.

The return of Major League Baseball also means the return of celebrity baseball fans like Ben Affleck (Red Sox), Jay-Z (Yankees), Snooki (Mets) and even President Barack Obama (White Sox).

These famous faces will surely be enjoying the game with a new season of hotdogs, beer, popcorn and pretzels, all from the comfort of their VIP seats.

Will baseball be seeing the famous face of Lady Gaga this season? Two years ago, the superstar was banned from the New York Yankees clubhouse after she was seen grabbing her chest and slurring her words, all while wearing a loose jersey, underwear, a bra and fishnets. At another game, weeks before the clubhouse incident, Gaga was also seen throwing a temper tantrum at Citi Field, where she apparently flipped the bird (with both fingers) to the crowd.

While most famous baseball fans are not famous for their stadium behavior, it's safe to say that Gaga will most likely stay away from baseball games for the time being. She's currently preparing for a massive world tour that begins Apr. 27.

But back to baseball. And all those celebrity fans. Here's a look at some famous faces and the teams they love.

Happy Opening Day 2012!

Lady Gaga Yankees
This fan sure knows how to draw attention. So much that in June 2010, Gaga was officially banned from the Yankees clubhouse after displaying some inappropriate behavior (slurring, messy whiskey drinking, groping her own breasts). REUTERS
Prince Harry Mets
OK, so this was an honorary visit in 2010, but Harry seemed pleased at the time to don the famous blue and orange. REUTERS
President Barack Obama White Sox
POTUS has hometown pride. REUTERS
Jay-Z Yankees
Jay-Z is such a hardcore Yankee fan that in 2010, the rapper made limited edition memorabilia. And he rode the float with the team the year before, when the Yankees were crowned World Champs. REUTERS
Jonas Brothers Dodgers
While the JoBros were born in New Jersey, the brothers are Dodgers fans. In 2009, the trio attended the team’s opening day game, where they watched the Dodgers beat the Giants in a landslide 11-1. REUTERS
Ben Affleck and Jennifer Garner Red Sox
They sure love their New England sports teams. REUTERS
Tracy Morgan Orioles
In 2010, Morgan threw the first pitch at the Orioles vs. Yankees game. Morgan actually has a baseball connection (sort of ): “I used to play for the Padres with Jose Uribe,” he joked with SB Nation after the game. REUTERS
Alyssa Milano Dodgers
Alyssa Milano has blogged about baseball, designed an clothing line for women who love baseball and in 2009 wrote the book "Safe At Home: Confessions of a Baseball Fanatic." It's safe to say Milano is fan enough. REUTERS
Nelly Cardinals
When the Cards won the World Series last October, the rapper took to Twitter (of all places) to express his excitement.“11 in 2011 IF U WIT ME let me see ya CARDS HAT and eleven!!all the way from china!” he wrote, all the way from China. Twitter
Mark Wahlberg Red Sox
Just like Ben Affleck, Wahlberg loves his New England teams. REUTERS
Jerry Seinfeld Mets

Kevin James Mets
If Kevin James had to choose between going to the Oscars or the Mets (in the World Series), the answer is obvious.“Listen, I don’t think either of them are happening so if I can dream, I’m going to the Mets series,” James told Popeater in 2011.James also named his second daughter after the former Mets home, Shea Stadium.
