Charli XCX shouts out ‘extremely brat’ Post columnist Andrea Peyser during ‘SNL’ monologue for her Martha Stewart takedown

Charli XCX shouted out the "extremely brat" New York Post columnist Andrea Peyser during her "Saturday Night Live" monologue for her Martha Stewart takedown .

"I have to say 'Brat Summer' has been a crazy experience. So many people have asked me, 'What is brat?' And honestly, it's just like, an attitude. It's a vibe," she said during the comedy sketch show late Saturday night.

"For example, the new Martha Stewart documentary. When Martha gets mad about an old magazine and she says that she's glad the journalist who wrote it is dead. That is brat," the "360" singer, 32, added.

"And then last Friday, when that exact journalist responded and said, 'Hey, I'm alive bitch!' That is extremely brat."

Charli, born Charlotte Emma Aitchison, was referring to the epic showdown between Stewart and Peyser last week.

In the interior designer's new Netflix documentary "Martha," she talked about her 2004 insider trading trial and how Peyser reported on what occurred in the Manhattan federal court.

"New York Post lady was there, just looking so smug," Stewart, 83, recalled in the doc of the day her guilty verdict was read.

"She had written horrible things during the entire trial. But she is dead now, thank goodness. And nobody has to put up with the crap she was writing all the time."

However, Peyser is NOT deceased and she hit back at the cookbook author in a scathing Post .

"I'm alive, bitch!" she wrote, adding that Stewart was "still fantasizing about my grisly demise."

"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 are not with her family, her pink-slipped employees, her mini-menagerie of animals, or even her own miserable self," the reporter added.

"She's focused her fury at me."

Peyser said Stewart is a "perfectionist so petty and abusive" and an "obsessive-compulsive" who is "so mean."

Stewart got wind of Peyser's latest and bitterly acknowledged the story while onstage at the Philadelphia Conference for Women event on Thursday.

"She wrote this very scathing today in the New York Post — my favorite newspaper," she sarcastically said.

The TV personality said the dialogue with Peyser would "probably cause more people to watch my documentary."
