George & Amal Clooney -- Home Is Where the Heart Is ... Covered with Cheese (TMZ TV)

When George Clooney returns to his hometown it's big news for the folks back home -- but when he brings his new wife? Well, that's HUGE ... possibly because he hasn't been married since 1993.

Anyway, yeah ... George took Amal back to see his Kentucky roots, and to stuff her full of pie!
