Martha Stewart definitely isn't keeping up with the Kardashians.

The 74-year-old lifestyle guru hilariously dissed Kim Kardashian's best friend, Jonathan Cheban, on Twitter, posting his picture on Wednesday, and asking the British tabloid, The Daily Mail, if they knew who he was. Stewart is currently in Cannes and was a guest at the Daily Mail's MailOnline yacht, where she was apparently seated by Cheban.

"#seriouslypopular @DailyMail @MailOnline Do you know this guy??" Stewart captioned Cheban's pic, referencing the "Seriously Popular" award the Daily Mail presents at the People's Choice Awards. "He says he is well known."

After plenty of fans responded, she posted yet another picture of 42-year-old Cheban.

"Better photo of Jonathan who is very famous bff of the Kardashians. Who knew!" she wrote.

Despite the amazingly shady tweets, it was all love on Jonathan's end, who later posted a pic of the two drinking wine.

"Best dinner with the best @MarthaStewart great time," Cheban captioned the Instagram.

"She's been keeping me laughing for hours!" he added on Twitter.

This, of course, isn't the first time Stewart has proved herself to be the queen of shade. Stewart's taken shots at everyone from Gwyneth Paltrow to Blake Lively and even the Netflix hit, Orange Is the New Black.

Stewart was also widely considered the best part of Justin Bieber's Comedy Central roast last March, when she poked fun at her 2004 prison stint while brutally taking jabs at the "Sorry" singer.
