Miley Cyrus -- New Home, Home on the Range (PHOTOS)

Miley Cyrus is reconnecting with her Tennessee roots ... she just bought a $5 million ranch in the outskirts of L.A. County.

Miley is now the proud owner of a 5 1/2 acre estate in super exclusive Hidden Hills, complete with a riding arena, a 10 stall barn, a chicken coop and a vineyard with 550 grape vines.

The ranch-style home is 6500 square feet and tucked safely inside a gated community. We're told Miley was looking for security after 3 break-ins at her Toluca Lake home in just a little more than a year.

It's ranch living, L.A. style.
