David Foster Gushes Over ‘Magical’ Wife Katharine McPhee

David Foster Gushes Over ‘Magical’ Wife Katharine McPhee, David Foster has had the happiest year of his life as Katharine McPhee’s husband.

“We’re doing great,” the star of David Foster: Off the Record exclusively reveals in the new issue of Us Weekly.

Since tying the knot, the couple — who celebrated their first wedding anniversary on Sunday, June 28 — have proven to have an unbreakable connection, and Foster, 70, credits that to their deep conversations. “She’s opinionated, super-talented, and along with that super-talent comes a big brain, and she’s got a lot to say,” he gushes. “It’s challenging, but in the best way possible.”

No matter what, “she has to keep pushing to make me answer things that I don’t want to answer, which is great,” he continues. “Her navigation skills are better than anybody’s I’ve ever seen and she’s super-evolved.”

Another plus? Foster’s children from his previous relationships — including Sara and Erin Foster — approve of the songstress, 36. “She’s really magical and able to float in and out of all the family dynamics,” David adds. “It’s amazing to watch because that’s a huge talent — being able to navigate my life.”

While the producer remained tightlipped about a family expansion, he did hint that music could be in their near future. “I think maybe we should make a record together,” says the 16-time Grammy winner. “I would love to and I think she would love to, and I think it would be really a cool thing to do. She has a great voice. We could make a great stream.”
