Watch : Martha Stewart Reveals "Jerk" Ex Andy Stewart's Reaction to Her DocMartha Stewart is cooking up realness. After the chef revealed in her 2024 documentary Martha that she engaged in an affair while married to her ex-husband Andy Stewart, the 85-year-old shared whether she’s heard from her ex—whom, at the time, she hadn’t spoken to in 20 years—following the revelation. “Only legally, to remind me of divorce settlement statements, which I had never read,” Martha—who split from Andy in 1990—told People in an interview published Aug. 5. Not mincing words about her ex, she then added, “He’s a jerk.” Because while Martha did admit to an affair, there was infidelity on both sides of her almost 30-year marriage.
