I'll Shut Up When You Pay me my money says Kim & Kanye's Ex-Bodyguard

As TMZ first reported, Kim and Kanye West are threatening to sue Steve Stanulis into the stone ages for breaking his confidentiality agreement. You'll recall he did a bunch of interviews claiming he was fired for chatting up Kim on the job ... which they deny.

Stanulis seemed to laugh off the threat Thursday in Staten Island, saying he's still owed money from his last gig with the Wests -- and insinuating he never signed any agreement.

As for his claim about back pay --  The security company that hired Stanulis is still waiting for him to turn in an invoice and expense report. So, he's only got himself to blame.
