Carrie Underwood Husband: 'I'd Quit' If My Husband Told Me To, Says Underwood

Carrie Underwood is a chart-topping superstar, but she'd give it all up for her husband, hockey player Mike Fisher.

"If Mike ever told me he needed me to quit, I'd quit," Underwood told People magazine Wednesday. "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."

Underwood also revealed that Fisher's fit body inspires her to keep in shape.

"Even when he's like, 'I'm so out of shape,' he still has a six-pack," she said. "Having Mike there -– I want to be a hot wife!"

Underwood and Fisher married in 2010. Underwood has commented on the strength of her marriage before -- earlier this year, she said that she has never worried about Fisher cheating because he "just wouldn't do that."
