20 Famous Friends Who Fell In Love
Katharine McPhee & David Foster
David Foster might not be a household name like Katharine McPhee, but the American Idol contestant’s husband is one of the biggest music producers in history. Good Housekeeping thinks the future couple met in 2006 when Katharine sang one of David’s songs (Whitney Houston‘s “I Have Nothing” — we told you, he’s a Big Effing Deal). We suspect their 34-year age difference is what kept their relationship friendly for so many years, but it doesn’t seem to bother the happy couple, who married in June 2019, or Kat’s new stepdaughters, who incidentally are older than their new stepmom.
