AceShowbiz - Kourtney Kardashian clapped back at allegations surrounding her work ethic in a series of tweets on Thursday, April 2, 2020 night.

The reality TV star, 40, hit back at critics as she and sister Kim Kardashian butted heads over long-simmering tensions about the Poosh creator's boundaries when it comes to filming their reality show.

During Sunday's March 29, 2020 season 18 premiere of "Keeping Up with the Kardashians", Kim accused her sister of not having a strong work ethic, leading to a physical altercation which the KKW Beauty mogul later described as "pretty intense."

Taking to twitter, Kourtney, who is mum to daughter Penelope, seven, and sons Mason, 10, and Reign, five, with ex Scott Disick, said, "I won't be live tweeting #KUWTK tonight, as I'm spending time with my kids while they are on spring break."

She continued, "I realize that a lot of the conversation right now surrounds my work ethic, and I feel like I need to just make one thing clear: raising children is a job as well."

"In fact, it's the hardest and most rewarding job that I have ever had. I've decided to put my focus on my kids and my lifestyle brand, Poosh, which is all about finding YOUR healthy balance for living your best life," she added. "I don't judge anyone who chooses a different route, and I hope that everyone can appreciate my choices as well."

Ahead of the season premiere, Kourtney's mum Kris Jenner said her daughter was "frustrated and felt under-appreciated," but confirmed she has returned to filming the family's reality show after stepping back for a while.
