Last month, the singer shared the first photo of son Rennie's face as she posted a series of pictures in honor of Father's Day.

Among the carousel of shots is one image of McPhee and Foster, 72, with Rennie, whose face can be partially seen looking down at a piano. The actress had previously hidden her little one's face entirely from view when sharing photos of him on social media.

In the caption of her post, McPhee paid tribute to Foster, whom she described as being the man "who loves me like I could have only dreamed of & who made me complete in life by making me a mommy."

"I love our little family. I love our big family," McPhee continued. "You have NEVER complained over how your life is slightly different now. Well… you only complain that you can't stay up late watching TV in bed but how can I blame you -that's your favorite thing."

Added the star, "You've only made bringing Rennie into the world an absolute joy for me. To many more adventures baby! 🎊I love you to the moon and back."

McPhee and Foster, who tied the knot in June 2019 after first meeting in 2006, welcomed their son in February 2021.
