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."
