The bronze-skinned Krentcil has become a media sensation following her arrest for allegedly taking her 5-year-old daughter to a New Jersey tanning salon.
Kardashian poked fun at the controversy on Twitter over the weekend by posting an image of her own impressive tan.
She also tweeted: "The tannerexic mum has some serious competition!!! LOL"
Kardashian's comment apparently caused complaints from some of her Twitter followers, prompting the reality star to offer clarification on the tan.
"Relax that's just a spray tan!!! It washed off & I'm back to my normal tan self! But how crazy does it look after being on for 8 hours," the Keeping Up with the Kardashians star wrote.
She added: "How do you spell tanorexic anyway? Tannerexic? Tannorexic? Is this even a real word?"
Jersey Shore's Nicole 'Snooki' Polizzi recently slammed Krentcil, insisting that the 'Tan Mom' is "crazy" for bringing a child to a tanning salon.
Krentcil responded by calling Snooki "the biggest asshole in the world" and declaring that she wants to "meet up" with the expectant mother.
