Kid Rock has been outed as a closet country music fan.

The rap-rocker, known for making music with heavier beats, is currently enjoying chart success with a mellow duet with Sheryl Crow called PICTURE.

And his fiancee Pamela Anderson insists Detroit native Rock's true love is country music, which he plays at every opportunity with friends like TRAVIS TRITT, Hank Williams Jr and Rascal Flatts.

She says, "I think everyone's really surprised, but, you know, I hear him play, like every night, play the blues, play with all his friends, and his friends are from Travis to Hank to Rascal Flatts - I mean, anyone that's around.

"This is the music that he plays. Everything else is sides of him too, but I think more so country."
