Fixer Upper stars Chip and Joanna Gaines are taking a wrecking ball to their marriage as fame and fortune push them apart! “Fame has changed both of them, and not for the better,” an insider exclusively tells Closer. “What was once a marriage is now mostly a business.”

Now, Chip, 49, and Joanna, 46, are focused on upscale renos, sparking conflict between them. “Joanna is pushing shows that focus on luxury renovation. Chip wants to focus on renovating modest homes. This business conflict has had a major impact on their marriage,” adds a source. “They have changed — but nothing has changed as much as their marriage!”
