Katherine McPhee and David Foster (With a 34-year age gap)
There are many fascinating tales about love relationships and how couples meet. During the fifth season of American Idol, when Katharine was a competitor, David Foster came to her house to assist her in practice because she would perform a song that he had composed.
In 2018, after meeting through David, Leah was paired with him as her mentor. Given the age gap between them, it’s no surprise that the press focused on their 34-year difference rather than the connection itself.
