Carrie Underwood is a good girl.  Pardon the play on words from her single, but Carrie opened up to  People Magazine about her marriage to Nashville Predators star Mike Fisher.

While Carrie has a career that is nothing short of stellar, she says there is one thing that would make her walk away from it all. That one thing would be her husband.

"If Mike ever told me he needed me to quit, I'd quit," Carrie says. "When you make that promise to somebody, and you stand before God and your family and friends, you've got to do everything that you possibly can to make that work."

Carrie graces the cover of People Magazine on the newsstands Friday, April 5th.
