Fans were more than a little sceptical that North, who will turn 8 in June, could have been responsible for such a professional-looking artwork.
As the online roasting spread across social media, Kardashian hopped back on Instagram to blast her doubters, telling critics to "stop embarrassing yourselves" and warning: "DON'T PLAY WITH ME WHEN IT COMES TO MY CHILDREN!!!"
A close friend of North's is also taking part in the art class and her mother was quick to jump to the young artist's defence.
"Both girls are in art class together and learning oil painting techniques from an instructor," the friend's mother, Tracy Romulus, explained via Instagram. "They spend weeks at a time on a single painting and are incredibly proud of themselves once they complete a project."
A TikTok user has also come forward claiming that her mother is North's art teacher, saying the child started art classes at her mother's Westlake Village studio just two weeks ago.
"My mum taught me how to paint this and she taught North how to paint the same one, just two weeks ago," TikToker Camryn Frederickson explained. "She's been an art teacher for 30 years and everyone who comes to her classes starts with the exact same painting when they're starting out."
