After noticing the cruel remark, Nadia hit back at accusations she doesn't have a "real job".
"Try writing from a real account. Don't hide. I have numerous real jobs," she wrote.
The relentless troll responded, calling her a "pretender" and a "try hard Kardashian", as well as saying "it's fascinating watching Nadia's world crumble when it was so "Insta perfect".
The hateful comments surfaced after reports claimed her estranged husband of five years, Jimmy— who she allegedly split from in July— had moved on and is now dating Melbourne socialite Lauren Mand.
"They're not talking," an anonymous friend of the Bartels' said about their currently bitter relationship. "It's definitely over. [Nadia] is completely blindsided."
"I am probably not going to provide any commentary on it," the 35-year-old said. "I know I am in the public eye and people are interested, but it is a private matter and I ask for a bit of respect because obviously Nadia and the boys [are] involved."

Earlier this month, eagle-eyed also noticed Nadia, 34, hadn't been wearing her wedding ring in her social media posts, adding to speculation they'd broken up. The seemingly perfect couple also unfollowed each other on Instagram, with many pointing out neither has appeared on their spouse's feed in months.
Though Nadia is yet to speak out, on August 14, a source told The Herald Sun that they had called it quits – and a cryptic story uploaded to Nadia’s Instagram appeared to suggest as much, too, hinting that she’s being comforted by the support of close friends at this time.
“People who resonate with your energy will always be there,” read the aspirational post she shared. “It’s soul family. Know your members.”
Nadia’s addition to the post was a kiss emoji with the words: “You all know who you are.”
The couple first got together in 2008 at the Melbourne F1 Grand Prix, and had been inseparable until recent times. They married at the Bellarine Peninsula in February 2014, and share two beautiful boys.
