48. Jennifer Garner
Favorite Team(s): San Francisco 49ers (NFL), Boston Red Sox (MLB), Boston Celtics (NBA)
Dated An Athlete?: No
Garner has her husband, Ben Affleck, to thank for her love of baseball and the Boston Red Sox, but she obviously just isn't in it for the hubby brownie points. Garner impressed Leno fans by reciting the Sox's lineup on live TV. Plus, she doesn't side with her husband's New England roots on everything, she is a diehard San Francisco 49ers fan.
