18. Brooklyn Decker
Favorite Team(s): Andy Roddick (Tennis), Carolina Panthers (NFL), North Carolina Tar Heels (NCAA Basketball)
Dated An Athlete?: Andy Roddick (Professional Tennis Player)
Sure, being married to tennis star makes you a tennis fan default, but Decker was spotted at almost every match her newly-retired husband Andy Roddick played in, including his last U.S. Open. The supermodel isn't new to cheering her favorites on, however. Decker was a cheerleader at Butler High School in North Carolina (which explains her Carolina Panthers fandom) and still occasionally tweets her support.
