9. Jennifer Lopez
Favorite Team(s): New York Yankees (MLB), Miami Dolphins (NFL)
Dated An Athlete?: No
Bronx-native Jenny from the block roots for the Yankees, of course. On her website, she also admits that she owns "over 30 New York Yankees T-shirts, 2 New York Yankees Jersey, 1 Yankees bag, 3 Yankees key chains, [and] 2 Yankees pencils." Given her dedication, we even suspect that her divorce from Marc Anthony might've had a little something to do with the fact that he's a Mets fan. Besides baseball, J-Lo is also in the know on football as she co-owns the Miami Dolphins.
