"Our family feels so blessed to have this beautiful new addition to our family," she said in a statement. "We cherish our lil Scout already and can't wait to watch her as she grows in this world alongside her sweet big brothers."
Jennings, 34, didn't realize she was actually five weeks pregnant when she and Misty May-Treanor won the Gold at the 2012 Summer Olympics.
Scout joins 3-year-old Joey and 2-year-old Sundance.
