Jessica Simpson has gone south... to my home state of Tennessee that is. 

Evidently the eldest Simpson daughter has moved to the Country Music Capital of the World for one reason.  It's the same reason every singer goes to Nashville - to record country music!

“Jessica has been writing music with John Rich of [country duo] Big & Rich,” one Nashville insider reveals to OK!

Jessica is soaking in all Nashville has to offer (which isn't much more than country music) with her dad-ager Joe Simpson and BFF Cacee Cobb.

Other celebrities who also have residences in and around Nashville include Reese Witherspoon, Reba McEntire, Nicole Kidman and her husband Keith Urban.
