The View cohost gave birth to a 7-lb. 15-oz. boy Friday morning at an Arizona hospital. Hasselbeck plans to call into the show Monday to announce her son's name.
The baby joins big sister Grace, who is 2.
"We're thrilled he arrived safely," Tim Hasselbeck said in a statement. "Both mom and son are happy and healthy."
The View cohost, 30, and her NFL quarterback husband, 29, moved to Arizona in October, after he signed a contract with the Arizona Cardinals.
The move brought early maternity leave for Elisabeth, who has pledged to return to the ABC morning talk show. When she had Grace, she took a total of six weeks off.
Hasselbeck first announced this pregnancy on her show in April.
