A New York Post columnist is clapping back at Martha Stewart − and letting the businesswoman know she's very much still alive.

In "Martha," a new Netflix documentary about the lifestyle guru's life, Stewart slammed columnist Andrea Peyser, who covered the TV personality's 2004 securities fraud trial, which landed her in federal prison. In the tell-all documentary, Stewart said of Peyser: "New York Post lady was there just looking so smug. She had written horrible things during the entire trial. But she is dead now, thank goodness."

In 2004, Peyser's coverage in the New York Post held no punches. She described Stewart's outfit as "dun-colored spike heels and a shapeless smock — looking like a gardener who moonlights as a dominatrix" and she accused Stewart of playing the victim during her trial, "a carefully scripted pose."

In a statement to USA TODAY Thursday, Peyser said, "I should be flattered I lived in her head all these years − and (that) she's (a) faithful Post reader."

On Thursday, the columnist also penned an article, titled: "Hey Martha Stewart, you gloated about the death of a Post columnist — but I’m alive, (expletive)!" She began, referring to her early aughts takedown of Stewart, "Even if the Domestic Dominatrix thinks she's finished me off … Two decades later, she’s still fantasizing about (plotting?) my grisly demise."

Peyser continued: "I made an uncredited cameo appearance in the new Netflix documentary, simply titled with her first name, 'Martha.' Like Cher. Or Osama." The columnist added that Stewart's portrayal in her Netflix doc appeared so "petty and abusive" and that "she's an obsessive-compulsive so mean."

USA TODAY reached out to representatives for Stewart for comment.

Martha Stewart criticizes Netflix's'Martha' documentary: 'I hate those last scenes'

"Long after she and her insider tip-giving stockbroker Peter Bacanovic were convicted of securities fraud and other crimes, then lying about it to federal investigators, her thoughts were not with her family, her pink-slipped employees, her mini-menagerie of animals, or even her own miserable self," Peyser continued, adding that Stewart "focused her fury at me."

Peyser also accused Stewart of never accepting "responsibility for committing felonies that stood to damage the American financial system," in reference to Stewart's infamous five-month federal prison sentence from October 2004 to March 2005 for lying to federal investigators about a stock sale. 

The columnist wrote she feels "pity" for Stewart, adding, "She's beautiful, creative and temperamental" and yet "she remains dangerously preoccupied with little, insignificant me."

Martha Stewart criticism comes after 'Martha' director, Ina Garten feud

In recent months, Stewart has spent time cooking up beef with people from her past from "Martha" director R.J. Cutler to Barefoot Contessa and ex-friend Ina Garten.

Last month, she took aim at Cutler, telling The New York Times that "R.J. had total access, and he really used very little," which "was just shocking." She also hated certain scenes from the film, telling the Times about her "hate" for them.

Martha Stewart says 'unfriendly'Ina Garten stopped talking to her when she went to prison

"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. I hate those last scenes. Hate them," she said. 

In September, Snoop Dogg's BFF called out Garten in a profile for The New Yorker about the latter's life and career, telling the outlet that Garten stopped talking to her when she went to prison for insider trading in 2004.

"When I was sent off to Alderson Prison, she stopped talking to me," Stewart told The New Yorker in an interview published on Sept. 9. "I found that extremely distressing and extremely unfriendly."

However, Garten told the outlet the former friends lost touch when Stewart spent more time at a new property in Bedford, New York.
