Not shared in the video, but Katharine also told US Weekly that Rennie is absolutely in love with his parent’s Christmas album:
“I swear to you that I do not play him songs of me so that I can hear myself all day long. But he’s now obsessed with … our Christmas album,” she said, noting “I’ll Be Home for Christmas” is Rennie’s go-to jam. “He’s obsessed with our version. I try to play him other people’s version, and he’s like, ‘No, no, no, no, no, no.’ And then he goes, and he can see on the Spotify which one it is, he sees our face and I have to listen to it over and over and over and over again.”– Katharine McPhee Foster to US Weekly
