How Old Is David Foster And Katharine Mcphee

Okay, picture this: a Grammy-winning music legend with a jaw that could cut glass marries a pop star young enough to be his daughter's playmate. No, this isn't a plot from a daytime soap opera. This is the real, gloriously absurd love story of David Foster and Katharine McPhee.

These two tied the knot in 2019, and the internet promptly lost its collective mind. The whispers, the tweets, the "wait… is she on his album cover or his wedding registry?" comments were endless.

Because when you hear "David Foster and Katharine McPhee are dating," your brain does a little cartwheel trying to process the timeline.

So, How Old Is David Foster?

David Foster was born on November 1, 1949 in Victoria, British Columbia, Canada. That makes him a proud 75 years old as of 2025.

This man has been alive for longer than color television listings existed on many channels—and he still looks like he steals moisturizer from very expensive hotel bathrooms.

He's got 16 Grammy Awards to his name, which is roughly 16 more than the rest of us will ever get. He's written, produced, or arranged songs for Whitney Houston, Celine Dion, Michael Bublé, and basically anyone who can hold a note.

And Katharine McPhee?

Katharine Lynn McPhee was born on February 25, 1984, in Los Angeles, California. That puts her at 41 years old as of 2025—and yes, everyone already did the math.

She rocketed to fame on American Idol back in 2005, nabbing the second-place spot behind Taylor Hicks but winning her place in our hearts. She later starred in the TV show Smash and Scorpion, keeping busy while the rest of us binge reality TV in pajamas.

At 41, she's still incredibly young—but in Hollywood years, she's basically a newborn who just learned to tap dance.

The Age Gap That Broke the Internet

Here's the part where everyone gasps theatrically: David is 34 years older than Katharine. Yes, thirty-four. That's a fully grown adult plus a Civil War and a decade of aggressive wedding planning.

Their son, Riley Foster, arrived in February 2021, meaning David welcomed a baby at 71. Most people are collecting Medicare discounts at that age, not collecting pacifiers.

Katharine, meanwhile, became a mom at 36—still young enough to chase a toddler while David battles him in spirited rounds of finger-painting.

And They're Still Going Strong

Despite the age gap and the endless eyebrows raised, these two have been making it work since 2019. They're spotted at dinners, premieres, and family outings—grinning like two people who've decided that love doesn't need a calculator.

Katharine has called their relationship lasting and genuine, while David's Instagram makes it clear he's happier than a producer who just remixed a No. 1 hit.

So there you have it: a 75-year-old musical genius and a 41-year-old pop icon, 34 years apart, and out here living proof that love doesn't check birthdays first. Who are we to judge? Pass the café latte—we're all just guessing anyway.
