The idea of working with David Foster was music to Katharine McPhee’s ears. The couple, married since 2019, have been enjoying their time together, doting on their son Rennie, whom they welcomed in February last year. But now, the pair have teamed up for another collaboration.

On November 25, the duo will release their first album together, “Christmas Songs,” a seven-track record of reimagined holiday tunes featuring a big band sound. “David and I met when I was a contestant on ‘American Idol,’ which was about 17-18 years ago,” the 38-year-old said about her spouse, 73.

“We’ve been colleagues long before we were in a relationship together,” McPhee shared. “Then we became friends. So I’m very accustomed to being on stage with him, sharing a stage with him, being in the recording studio with him. That was first before anything. That’s where we’re the most comfortable together. It doesn’t create any friction between us at all. There’s no kind of unknown between us. That’s where it all started for us.”

McPhee and Foster began dating back in 2017. The “Smash” alum previously noted that the record producer threw a Christmas party to impress her and her friends. McPhee shared that their idea of keeping the spark alive as busy parents has gotten “really simple” over the years – and she would not have it any other way.

“We just love being able to go to a movie and have dinner together,” said McPhee. “There’s nothing extravagant about what we like to do. We just want to reconnect. I love to just sit and have dinner with him. I’ll have a glass of wine – he doesn’t drink. And we just talk. That’s our time together that we always make sure to have. We have a very hectic schedule, so that’s really important to us to carve out that time each day. And there’s always something to talk about whether it’s our family, our son – it’s our time.”

McPhee said the quality time she and Foster shared at the studio bonding over Christmas songs brought them even closer together. “I’m always marveling at his ability to have an idea in [his] head and manifest it into something,” she explained. “Working with David is the best because he knows exactly what he wants, what he needs from you. Being his wife and also his fan before we were even married, I have an immense respect for him. And it’s been so much fun. We had the summer together and thought about just releasing a few songs on social platforms, but the idea turned into so much more.”

McPhee insisted that her son is already showing off his musical talents. Time will tell if he goes on to pursue the family business, but the star said she already knows the piece of advice Foster will give on pursuing the music industry. McPhee says that Foster will tell their son that he’s the only one that can figure things out for himself.

Many would think that with such a significant age gap, it would be challenging for this couple to keep things fresh. However, McPhee and Foster are prime examples of keeping your marriage alive at any age.
