Katharine McPhee is Katie Holmes' doppelganger!
It just hit us how much American Idol star Katharine McPhee looks like Katie Holmes!! Their facial expressions, body language, hair, even their first names are the same. We're starting to fear that when Katherine McPhee sings at Katie and Tom's wedding she might disappear and be iced down as a back up to Katie.
