We have seen some unexpected pairings among celebrities. Some started as rumours before they were publicly announced or confirmed. Katharine McPhee and David Foster was shocking to me. They met on American Idol (2006) when Foster was a guest mentor and Katharine was just a contestant. David Foster was already successful and the age difference was huge. He had a son with Katharine in 2021- there is a 50 year gap between Foster's first and youngest child. What's the most surprising celebrity couple you've ever heard of?
