Martha Stewart once had an extramarital affair that her husband never knew about.
The 83-year-old businesswoman was married to Andrew Stewart from 1961 until 1990 and has daughter Alexis, 59, with him but while she lambasted any man who was unfaithful to his significant other, admitted that she had in fact had her own affair prior to the end of her marriage.
Speaking in the trailer for her upcoming Netflix documentary 'Martha', she said: "Young women, listen to my advice. If you're married and your husband starts to cheat on you, he's a piece of s***."
The TV star was then questioned about her own affair, to which she replied: "Yeah, but I don't think Andy ever knew about that."
The former talk show host - who made her estimated $550 million fortunate through publishing, broadcasting, merchandising and e-commerce ventures - also noted int the trailer that she could have chosen to just be a housewife but is pleased that she took the plunge into business.
She said: ""I coulda just been a miserable, has-been housewife. But I didn't let that happen to myself. And I'm so happy I didn't."
Following her divorce, Andrew went on to marry Robyn Fairclough in May 1993, who had worked as Martha's personal assistant, but they later divorced and he is now married to Shyla Nelson, with whom he has five children.
Meanwhile, Martha had a brief relationship with Hollywood star Anthony Hopkins and then dated tech billionaire Charles Simonyi on and off for 15 years before they called it quits for good in 2008 but she has not been linked to anyone publicly since.
She previously told E! News: "I know a lot of eligible men. I think they really want a woman who will take care of them, so I'm still not quite in the position where I can take care of a man full-time because I work too much."
