A rep for the Modern Family actor confirmed the news this morning, reports E!.
The announcement comes two weeks after the star spoke about his character Phil and expressed a strong desire to have kids of his own.
"[Phil] really is putting in the time, and he really cares about his kids even though he gets very few things right. I do love how much he tries, you know what I mean? If my wife and I ever have kids, I hope I can try as hard as Phil. Maybe not quite as hard as Phil, but I hope I can try," he said.
No other details have been released about the child.
