Wifey Of: Tony Romo, Dallas Cowboys (NFL), Mike Fisher, Ottawa Senators (NHL)
Between traveling on her world tours and recording platinum albums, the former American Idol winner has also found a way to date several of America's finest athletes. She was first linked to Tony Romo in 2007, although interestingly she never confirmed that they dated; she claimed that the two were just friends, while Romo was so bold as to post on his own website, "I'm dating Carrie Underwood." The relationship (if it even existed outside of Romo's mind) didn't last, and Underwood subsequently moved on to former Ottawa Senator and current Nashville Predator Mike Fisher. They were married in 2010 at a wedding so star-studded that even Paula Abdul secured an invite.
