Television show will air in the U.S. on July 23, 2013.
The U.S. version of the Who Do You Think You Are? television program will feature songstress Kelly Clarkson on one its upcoming episodes. Clarkson's ancestry is a mix of Greek, German, and Irish. However, she considers herself to be "mostly Greek" and she even speaks the language fluently. Most of the shows feature the guest celebrity returning to their ancestral homeland so it should be interesting watching her speak Greek, assuming she does visit Greece.
