Martha Stewart makes major mistake while being a ‘brat’ with Charli XCX

Social media mishaps happen.

Martha Stewart hung out with Charli XCX this week but made a crucial mistake when she tried to share the “brat” moment on social media.

The domestic doyenne, 83, posted a phot of her and the “365” singer Friday on Instagram, showing the pair looking incomparably “brat.”

However, Stewart tagged the wrong social media account — @charlie__xcx rather than @charli__xcx — misspelling Charli’s name with an “e” at the end.

Stewart deleted the pic shortly after posting it, likely realizing the error.

“Just hanging out with none other than @charlie__xcx who was actually not the BRAT she is known to be !” she captioned the snap.

“She has an awesome collection of dark and very large shades,” she continued before adding, “And she has very nice black hair.”

They sat in director’s chairs in what appears to be a studio with bottle of champagne and two filled flutes resting on top of a black trunk in front of them.

The straight-faced pair look directly ahead and into the camera, their eyes shrouded by dark black sunglasses.

Stewart pairs her oversized square shades with a chambray button-down shirt and shiny black leggings.

Charli opts for a rounder set of black sunglasses, and wears a loose black top with sheer black sleeves.

Stewart’s hangout with Charli comes one month after the “Apple” songstress praised Martha during her “Saturday Night Live” opening monologue as a paragon of “brat” because of her feud with The Post journalist Andrea Peyser.

Charli declared that to understand what it is to be “brat,” one need look no further than Stewart and Peyser’s tet-a-tet — which began when Stewart gleefully claimed in her new Netflix documentary that Peyser was dead, and ignited further when Peyser clapped back, telling the cookbook queen, “I’m alive, bitch!”

“Honestly, it’s just like an attitude,” Charli said. “It’s a vibe. For example, the new Martha Stewart documentary: When Martha gets mad about an old magazine article and she says that she’s glad the journalist who wrote it is dead, that is ‘brat.’”

The singer added, “And then last Friday, when that exact journalist responded and said, ‘Hey I’m alive, b-tch!’ That is extremely ‘brat.’”

After the “SNL” episode aired, Peyser exclusively told The Post, “Word to Mistress Martha: I’m still alive. B-tch. I’m floored to be called ‘extremely ‘brat’ on SNL. And thrilled that Martha Stewart is merely ‘brat.’ I am, however, still a bit frightened to have lived so long, rent-free, in Martha’s head.”

Stewart, meanwhile, conceded that Peyser’s was, in fact, alive and responded to her column at the Philadelphia Conference for Women on Nov. 7, saying of Peyser, “She wrote this very scathing article today in the New York Post — my favorite newspaper.”

Stewart then quipped, “So, that will probably cause more people to watch my documentary.”
