Kim & Kanye Threaten to Sue Former Bodyguard for at Least $10 Million

Kim Kardashian and Kanye West are going after a former bodyguard for talking smack about them -- something he's done before -- and warns if he opens his mouth again ... he can expect a multi-million dollar lawsuit.

The couple fired off a cease and desist letter to Kanye's ex-bodyguard, Steve Stanulis, claiming he went on the "Hollywood Raw Podcast" a few weeks back and made "false and defamatory" statements ... while also breaching their confidentiality agreement.

According to the letter, Kim and Kanye claim Steve signed the agreement in February 2016, and it prohibits him from blabbing any personal or business info about them ... something they say he did big time on the podcast.

If you missed it, Stanulis claimed Kanye had "ridiculous rules" -- like walking 10 paces behind him on city streets, and claimed he got angry if Steve blocked a paparazzi shot. He also called Yeezy the "moodiest" and "neediest" celeb who's hired him.

Kim and Kanye don't specify which of Steve's statements are false and defamatory, but they're threatening to sue him for at least $10 million for breaching their confidentiality deal ... if he does it again.

Here's the thing, though -- this isn't the first time they've threatened Stanulis for the same thing. It happened in May 2016 as well, but back then they also demanded a public apology. They didn't ask for an apology this time around.

We reached out to Stanulis, who switched careers in 2016 and is now an actor and director ... he has been working on a movie called "5th Borough" starring Tara Reid, which comes out June 3rd.

His publicist, Zack Teperman, tells us "... no breach of any confidentiality agreement was done. My client went on a podcast to promote his new film, and old stories that were already out there were brought up."

He adds ... "For Kanye and Kim's counsel to send out a threatening letter to bully my client against his rights is unwarranted. My client has already made it clear that he respects Kanye, their time working together."

Teperman says, "If Kanye and Kim wish to continue this further, that is up to them, but I think their time and money would be better suited helping out with more pressing matters in our society than what happened many years ago."
