Kourtney Kardashian has a very simple message for Michael Girgenti:
Zip it... OR ELSE!
Following years of this male model claiming he was the real father of Mason Dash Disick, Kardashian got a DNA test done in August that proved the toddler is stuck with Scott Disick as a dad.
But Girgenti has continued to scoff at these results and keeps issuing threats to Kourtney, telling her that he'll only shut up about Mason's paternity if she pays him some serious cash.
And Kourtney simply isn't taking it anymore.
TMZ has obtained a cease-and-desist letter written by Kardashian's lawyer, Shawn Holley, that makes it clear to Girgenti: end this extortion plot or face a lawsuit.
The letter also points out that Girgenti knows he's a liar, considering he failed a polygraph live on television.
Seriously, Michael. It's hard to make Scott Disick look good, but you're doing a bang up job of it. Just go away.
