Jessica Simpson's quarterback beau Tony Romo describes her to Vanity Fair as a "supportive girlfriend," while Simpson describes herself as a "crazed" Dallas Cowboys fan.

"I've never dated a guy that was more simple," the singer says of Romo. "I'm always there for him after a game, and he knows he has me to come home to."

The football player tells the publication that Simpson has a "small town side to her." "We're very similar in that we both appreciate the hometown feel to a lot of things, and live our life like that," he says of his relationship with Simpson. "She comes to a ton of games. ...She's a supportive girlfriend."

"I was always a fan," she told Vanity Fair regarding her love for the football team and support for her boyfriend. "In Texas, it's a sin not to be. But I've never been as passionate as I am now. Before a game, I'm crazed, sending mass e-mails: 'Please pray for Tony's protection.'"
