Before we get started — YES, Katharine McPhee Foster is 38 and her husband, David Foster is 72. Look, there's no denying Hollywood is filled with age-gap relationships, it's kind of like what Hollywood is known for. I mean, also like moves and stuff but, an older man marrying a young woman is a tale as old as time.
Of course, the most scrutinized age-gap couple is Katharine and David, who have 35 years between them.
