Kim Kardashian’s best friend Jonathan Cheban is clearly a mover and a shaker — he hangs out with the Kardashians, for God’s sake! But after seeing his blow-up with a business partner on last night’s episode of Kourtney and Kim Take Miami, we want to know: What does Jonathan Cheban do for a living?

Contrary to Kourtney’s not-so-nice opinion, Jonathan does not follow Kim around as his full-time job. He owns five companies!

Jonathan started his career in public relations. He founded his company Command PR in 1999, and it's going strong today — the company even got its own reality show, The Spin Crowd, in 2010.  

He also owns accessories line Rich Rock Jewelry and The Elite Daily, a website that touts itself as “The Voice of Generation Y,” and he recently opened a Florida outpost of the popular new York restaurant Sushi Mikasa in Miami!

In case you were in doubt about this man’s work ethic, Jonathan took to Twitter to clear things up:  “Yes people I work and own 5 companies.. I'm not tuning around with Kim...really people??”

Hmmm, we’re only counting four projects so far! But don’t worry, Jonathan cleared that up too. A later tweet mentioned a new burger franchise, and a little digging turned up the name: Burger Bandit. Apparently, Jonathan is looking to open an old-school burger joint in Florida soon, and spread it everywhere else soon after!

And remember, Jonathan was once also writing a book, he launched the clothing line called Kritik, and was planning a Reality Cafe in Las Vegas, but sadly (?) that project fell through. Say what you will about Kim K’s bestie, the man likes to stay busy!
