The Yankee's infielder is celebrating his 37th birthday today.

Unfortunately, the baseball star received a painful present at the Mariner-Yankee's game on Tuesday: a fractured left hand.

To turn that frown upside down, we thought we'd compile some interesting facts (that perhaps you didn't want to know) about the Dominican-American baseball player. So sit back, relax, grab some popcorn and take a look at the many sides of A-Rod.

YOU KNOW YOU WANT TO KNOW, EVEN THOUGH WE SAID YOU DIDN'T:

  • 1) Blondes! Blondes! Blondes!

    A-Rod seems to have a slight <a href="http://www.zimbio.com/Alex+Rodriguez/dating" target="_hplink">weakness for blondes</a>! The baseball player dated actress Kate Hudson in 2009, and a few months after their break-up he was spotted with golden haired star Cameron Diaz. As if that wasn't enough, before Kate and Diaz, A-Rod was rumored to have been with Madonna.

  • 2) He Owns A Mercedez Dealership

    A few sports cars in the driveway isn't enough for A-Rod, he needs a whole lot. The Mercedez-Benz dealership, named "<a href="http://www.arodmercedesbenz.com/" target="_hplink">Alex Rodriguez</a>," is located in League City, Texas.

  • 3) He Likes His Popcorn Hand Fed

    At Super Bowl 45, A-Rod's ex-girlfriend, Cameron Diaz, was spotted awkwardly <a href="http://www.huffingtonpost.com/2011/02/06/alex-rodriguez-fed-popcor_n_819338.html" target="_hplink">feeding</a> the baseball star. Diaz addressed the incident on the 'Late Show With David Letterman,' saying it was a playful moment when Rodriguez reached for one of the last pieces of popcorn in the bucket, and she denied him. Then, she told him, <a href="http://www.aoltv.com/2011/06/21/cameron-diaz-feeds-popcorn-to-david-letterman-on-late-show-vi/" target="_hplink">"You know what, I love you too much. I'm gonna give it to you. You deserve it."</a>

  • 4) He's Half-Horse

    Well not exactly, but in 2009 an "ex" told US Weekly an interesting fact about A-Rod's home decor. <a href="http://www.usmagazine.com/celebrity-news/news/ex-alex-rodriguez-had-portraits-of-himself-as-a-centaur-over-his-bed-20093010" target="_hplink"> "He had not one, but two painted portraits of himself as a centaur. You know, the half man, half horse figure?"</a> Oh, we know.

  • 5) He Has No Problem With PDA

    We knew him and Derek Jeter were close, but this image really takes the cake. It's ok A-Rod, a little 'Bromance' never hurt anybody.

  • 6) He Likes To Kiss Himself In The Mirror

    It looks like Jeter has a litte competition! In 2009, the baseball star did a photo shoot with <em><a href="http://www.details.com/celebrities-entertainment/cover-stars/200903/photos-of-yankee-alex-rodriguez#slide=1" target="_hplink">Details</a></em> magazine in which he posed in tight shirts longingly staring at himself in a mirror. It's important to love yourself, and Alex isn't afraid to show it.

  • 6b) A-Rod and The Mirror Spoof

    We just thought you'd really enjoy this Jimmy Fallon spoof....Now to #7!

  • 7) He Likes To Play Guitar In His Underwear

    The truth is he's just like us! (and Tom Cruise) On any given night A-Rod likes to gather a group of his closest celeb friends and rock out.

  • 8) He Likes Showing Off His Underwear

    We're not completely sure what A-Rod is doing with his athletic cup here but it seems like rocking out in your underwear isn't enough, he has to showcase them in the dugout as well.

  • 9) There's A Stadium Named After Him

    In 2003, being the good University of Miami alumnus that he is, Alex donated $3.9 million to renovate the baseball stadium. In his honor it was renamed <a href="http://sports.espn.go.com/mlb/news/story?id=3906391" target="_hplink">"Alex Rodriguez Park at Mark Light Field."</a>

  • 10) He Likes To Slap Balls

    The incident occurred during a Yankees-Red Sox's game in 2004. When the Sox's Bronson Arroyo tried to tag A-Rod with the ball, the Yankee's star simply <a href="http://sportsillustrated.cnn.com/multimedia/photo_gallery/1102/alex.rodriguez.worst.moments/content.1.html" target="_hplink">slapped it out of his glove</a>! It was later ruled as "interference" and his run was nullified. Didn't his mother ever teach him to keep his hands to himself?
