Martha Stewart’s ex-husband ‘furious’ about documentary revelation

America’s favorite housewife was also a homewrecker.

In her upcoming Netflix documentary, Martha Stewart reveals that she cheated on her ex-husband, publisher Andrew Stewart, and thought he never found out.

“Young women, listen to my advice: if you’re married and your husband starts cheating on you, he’s a piece of shit. Get out of that marriage,” Martha says in the film’s trailer.

In the doc, titled “Martha,” which premieres Oct. 30, a producer then asks the 83-year-old entrepreneur, whose net worth is about $400 million, “Didn’t you have an affair early on?” and she replies, “Yes, but I don’t think Andy ever knew about that.”

Andrew Stewart, who cheated on Martha with her ex-assistant Robyn Fairclough and left the “Martha Stewart Living” host after 29 years of marriage, is “furious” about the candid revelation, NewsNation’s Paula Froelich reported.

“Neighbors of Andy and his children say the publisher is furious because he is very private and feels like he is being dragged into the drama… again,” Froelich said.

The couple, who divorced in 1990, welcomed their daughter, Alexis, 59, a TV and radio host, in 1965.

The Post contacted Andrew Stewart for comment.
