Foster joked to PEOPLE in February that Rennie is just as musical as his parents, sharing, "He plays Mozart and Bach flawlessly," before adding more seriously, "At 11 months? ... Obviously, we don't see any musical talent yet, but who knows?"

Rennie is McPhee's first child and Foster's sixth. The music producer is also dad to daughters Sara, 41, Erin, 39, and Jordan, 35, with second wife Rebecca Dyer, and daughters Allison, 52, and Amy, 48, from previous relationships. McPhee and Foster tied the knot in June 2019 after first meeting in 2006.

"It's too cliché to say 'Now I have more time,' but I do: I have more time," Foster explained of being a dad again. "Without any reflection on any of my other children, whom I all love equally, and equally as much as my son."

While speaking to Entertainment Tonight at Clive Davis' 90th birthday celebration in April, McPhee and Foster raved about raising their little one.

"It's great. It's the best," the actress and singer said, while her husband added, "She's a fantastic mother. An amazing mother and we are having the best time."

McPhee told ET she was "having so much fun" as a mom, despite some sleepless nights.

"I love it, absolutely. I mean, last night was a little rough, the time...he was up and then you know, when you're traveling with the kid, you have your moments where you get over-tired and frustrated," she said.

"But it's just so precious because it's just a moment in time that is not going to last forever, so, in my perspective I just cherish."
