How Old Is David Foster And Katharine Mcphee

Ever wonder about the age gap between music mogul David Foster and his wife, singer Katharine McPhee? It’s one of Hollywood’s most talked-about couples, and the numbers behind their love story are surprisingly juicy. Whether you’re a fan of their music or just love a good celebrity fact, this age difference makes for fascinating dinner party trivia.

The Quick Answer

As of 2024, David Foster is 75 years old, born on November 1, 1949. Katharine McPhee is 40 years old, born on March 25, 1984. That gives them an age gap of exactly 34 years and five months.

Yes, you read that right. David was already a legendary producer winning Grammys when Katharine was just a toddler in the 1980s. It’s a gap that makes people pause—and then smile when they see how happy they are together.

How Did They Meet?

Their paths first crossed in 2006 on American Idol, where David was a guest mentor. At the time, Katharine was a 22-year-old contestant, and David was a 56-year-old music icon. Fast forward to 2017, they reconnected while working on a TV show and started dating in 2018.

“We were friends for over a decade before romance blossomed,” Katharine once shared. “I never imagined this, but life has a funny sense of timing.”

The couple got engaged in 2019 and married in a stunning London ceremony in June 2020. Their wedding was intimate, with only immediate family present due to the pandemic. Today, they share a son named Rennie, born in February 2021.
