It’s not always easy for Car­rie Under­wood and her hus­band Mike Fisher to see each other with their busy sched­ules, but they’re going to let every­one know how they make mar­riage work. They’ll be on the sea­son pre­miere of “Oprah’s Next Chap­ter” this Sun­day on the OWN net­work. Oprah inter­viewed the cou­ple at their cabin retreat in Nashville. They also took Oprah to their plot of land where they plan to build their dream home.
