Martha Stewart's one line comeback about her affairs in new Netflix documentary goes viral as fans hail the 'savage' 83-year-old

Martha Stewart 's fans are lapping up her relationship advice 40 years after she shot to fame as the 'perfect' homemaker.

The 83-year-old has been hailed as an icon by Gen-Z who have devoured the new Netflix documentary chronicling her career.

Whilst the R.J. Cutler film reveals all from Martha's troubled childhood, to her billionaire status and her infamous incarceration, it's the lifestyle expert's quips about men and her relationships which have gone viral.

Early scenes in the doc show Martha visibly raging as she recalls her ex husband Andy Stewart's affairs, telling viewers: 'Young women, listen to my advice, if you're married and your husband starts to cheat on you, he's a piece of s**t. Get out of that marriage.'

The producer then quips: 'Didn't you have an affair early on?' to which Martha replies, 'Yeah, but I don't think Andy ever knew about that.'

'She didn't flinch. Gave me chills,' hailed one fan, whilst another called her 'a savage.'

'Martha Stewart did some girl math in her documentary!' agreed one more as another admitted that 'finding out Martha Stewart cheated not once but twice got me cackling in my living room.'

In the film Martha revealed that she strayed during her 29-year marriage , including a passionate liason on her honeymoon.

Martha recalls kissing a 'very handsome guy' in Florence's Duomo di Milano on her European honeymoon while Andy was back at their hotel.

'He didn't know I was married,' she recalls on camera 'I was this waif of a girl hanging out in the cathedral on Easter Eve. He was emotional. I was emotional. It's just because it was an emotional place. It was unlike anything I'd ever experienced.'

She went on to share that she once had a 'very brief affair' with a 'very attractive Irish man' while she was working as a stockbroker in the late '60s but insisted 'it was nothing,' and 'I would never have broken up a marriage for it.'

Martha started dating Andy — who has been her only husband to date — when she was just 19 and he was 23, after they were set up on a blind date.

The couple married in 1961 and welcomed their daughter Alexis in 1965. However, by 1987, the pair had separated and their divorce was finalized in 1990.

'He was not satisfied at home,' she says in the documentary. 'I don't know how many different girlfriends he had during this time, but I think there were quite a few.'

She recalls the affair that broke their marriage , revealing that Andy had 'some sort of involvement with the girl who was doing the flower arrangements' at their home - Turkey Hill Farm.

Martha says her employee needed a place to stay, so she invited her to move into an apartment on their property but 'when I was traveling, Andy started up with her. It was like I put out a snack for Andy.'

'Andy betrayed me, right on our property,' she continues. 'Not nice.'

Whilst fans have hailed Martha, the star herself has criticised her own documentary , revealing that she 'hated' the final scenes and believed the second half to be 'a bit lazy'.

'Those last scenes with me looking like a lonely old lady walking hunched over in the garden? Boy, I told him to get rid of those. And he refused,' she raged. 'I hate those last scenes. Hate them.'

Speaking to The New York Times , Martha explained that she had ruptured her Achilles' tendon and had recently had an operation, hence the limping.

'But again, he [R.J.] doesn't even mention why — that I can live through that and still work seven days a week,' she quipped.

Martha was particularly irritated about R.J. using the 'ugliest' camera angle, despite her insisting that he should change it.

'He had three cameras on me,' she said. 'And he chooses to use the ugliest angle. And I told him, 'Don't use that angle! That's not the nicest angle. You had three cameras. Use the other angle.' He would not change that.'

If that wasn't enough, Martha expressed upset over the documentary's music too, confessing that she would have preferred if rap music had been used rather than the classical score that R.J. went for.
