Chip and Joanna Gaines have been married for 18 years, and in that time, they’ve worked hard to become successful enough to be a household name. The husband-and-wife home improvement duo started out with their wildly successful Fixer Upper series on HGTV and then turned that into an entire home improvement empire complete with a business complex in Waco, Texas, multiple books, a Target home accessories line, and their very own entertainment network. On top of all of that, they’ve also managed to parent five children as well.
