Katharine McPhee, David Foster welcome first child together

McPhee and Foster, who tied the knot in 2019, welcomed a baby boy

Congratulations to Katharine McPhee and David Foster on their newborn baby.

Fox News can confirm that the couple recently welcomed their first child together -- a son. 

"Katharine McPhee and David Foster have welcomed a healthy baby boy," McPhee’s rep also told People magazine on Wednesday. "Mom, Dad and son are all doing wonderfully."

In December, McPhee confirmed the pregnancy news via Instagram. She shared a glowing mirror selfie, which featured the 36-year-old donning a light blue double-breasted jacket while showing off her baby bump. Rumors arose that she and Foster, 71, were anticipating a child after the pair were spotted in October shopping for baby essentials in Montecito, Calif.
