12. Stacy Keibler
Favorite Team(s): Baltimore Ravens (NFL)
Dated An Athlete?: David Flair (Professional Wrestler, WWE), Andrew Martin (Professional Wrestler, ECW)
Keibler started to cheer for the Ravens when she was 18. We don't mean just root for them; she was an actual cheerleader before appearing in the WWE ring and dating George Clooney. As a testament to her dedication, Keibler, who's still seen rooting for Ravens, once used her $10k winnings from becoming a Nitro Girl to buy season tickets.
