Do you know who Jonathan Cheban is? If the answer is "yes," then you're clearly familiar with "Keeping Up with the Kardashians," the Kardashians' reality show that has been on for twelve seasons (!) now. If the answer is "no," though, don't worry, because you're not the only one.
Martha Stewart sent Twitter into a tizzy on Wednesday when she tweeted that she, too, had zero idea who Jonathan Cheban was.
"Do you know this guy??" she asked The Daily Mail alongside a photo of Cheban. "He says he is well known."
Stewart clearly doesn't watch "Keeping Up with the Kardashians" very often, as Cheban is frequently featured on the hit E! show as Kim Kardashian West's best friend. (For an example, watch the clip above of Cheban introducing Kardashian West to a Kim K. look-alike.)
Soon after, Stewart followed up her seemingly shady tweet with a "better photo of Jonathan, who is very famous BFF of the Kardashians."
After Twitter went absolutely insane about her tweet, Cheban proved that maybe he was in on the joke, posting a photo of himself with Stewart saying, "Fun dinner with the best!! She's been keeping me laughing for hours!"
The pair is evidently at Cannes Lion in the South of France at a Daily Mail dinner party. So, though Martha Stewart know does know who Jonathan Cheban is, she most definitely didn't before sitting down for dinner on Wednesday night.
