its not me

Nobody has Miley Cyrus' back like Disney.

TMZ has learned some seriously concerned big wigs at the company informed the LAPD about the recent arrest of a 53-year-old obsessed fan in Georgia who claims Miley sends him "secret messages" through her TV show.

Georgia cops arrested Mark McLeod for disorderly conduct on June 23 in Tybee Island, GA -- and during the incident cops say the guy made some very frightening statements about Miley.

According to the police report, McLeod claimed he was "great friends with Miley" -- and that Miley had "told him to come see her today."

Cops say McLeod also said, "I will f***ing be with Miley ... we're supposed to be together and [the cops] couldn't stop it."
