"Katharine McPhee and David Foster have welcomed a healthy baby boy," the spokesperson said, adding: "Mom, Dad and son are all doing wonderfully."

The baby is the pair's first child together, and Foster's first son, having fathered five daughters from previous relationships.

The happy news emerges a day after McPhee appeared in a pre-taped interview on the Women on Top podcast, in which she revealed she was expecting a boy.

"Now that I am having a boy, there are different things I need to worry about to teach him versus the things I would be thinking about with a girl," she told hosts Roxy Manning and Tammin Sursok. "But it's kind of refreshing because I feel like I don't need to think about those societal 'this is the way you look.' I think men have different issues and different things to worry about."

McPhee and Foster wed in London in 2019.
