Mariah Carey's former security company has threatened to sue her ... and the guy who owns the company says she constantly humiliated him by referring to him as a Nazi, a skinhead, a KKK member and a white supremacist.
Michael Anello's lawyer has prepared a draft of a lawsuit, claiming his company worked for Mariah from June 2015 to May 2017 and got stiffed on the balance to the tune of $221,329.51. Anello claims he was promised another 2 years which would add $511,000 to the tab.
