KRIS HUMPHRIES TO MEET WITH FBI

Kris Humphries has enlisted the FBI to do battle with his ex -- but not Kim Kardashian.

Radar Online reports that Kris is asking the feds to investigate Myla Sinanaj for allegedly trying to extort millions of dollars from him by going to the press to spill "secrets" about him.

A rep for the baller, who claims Myla was nothing but a booty call, tells the site, "Kris had to go to the FBI because he truly believes Myla is capable of making up crazy lies about him. Kris will fully co-operate with the FBI and do anything that's asked of him."
