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.

McPhee and Foster, who also has five children from previous relationships, tied the knot at a church in London in June 2019. The couple first met in 2006 when McPhee was a contestant on the fifth season of "American Idol" and Foster was a mentor on the singing competition series.
