Kim and Kanye Threaten Blabbing Bodyguard with $30 Mil Lawsuit

7:57 AM PT -- A rep for Kim and Kanye tells us the money won't be enough ... they also want a full retraction of everything he said in the interviews.

Kim and Kanye have threatened their former blabbermouth bodyguard with a $30 million lawsuit, and he's gotta drop to his knees and apologize.

We've learned Kim and Kanye's lawyer has fired off a letter to Steve Stanulis ... the bodyguard who went to anyone who would listen, claiming he was fired for chatting up Kim on the job and making Kanye jealous. Kim and Kanye have both said it's a complete lie.

Turns out, we're told that Steve signed a confidentiality agreement promising never to breathe a word about Kim, Kanye or the klan. We're told the lawyer's letter is quick to mention a provision which says Steve is automatically on the hook for $10 mil if he opens his mouth ... and they believe he did at least 3 interviews.

It's interesting. We're told Kim and Kanye's lawyer gives Steve an out, if he shuts his trap and issues a public apology to the family. Our sources say the letter does not ask Steve to admit he lied but they demand he stop talking to the press.

Kim and Kanye think Steve's MO is simple ... it's a cheap, underhanded way to get famous. A rep for the couple tells us, "This sad, parasitic maniac has violated every basic human tenet of decency with his story of lies. The Wests will explore all legal means at their disposal to silence this nonsense."

BTW ... this isn't the first time Kim and Kanye have gone after someone for violating the confidentiality agreement. TMZ broke the story, YouTube founder Chad Hurley weaseled his way into AT&T Park in SF and videotaped Kanye's marriage proposal. Chad signed a confidentiality agreement and ended up paying them $440,000.
