"We are so overjoyed. What an amazing, wonderful and overwhelming experience to welcome our daughter into the world," Lopez told "Extra," the television entertainment news program for which he is anchor.
Lopez and Mazza met in 2008 when they appeared together in the Broadway musical "A Chorus Line."
Their daughter, Gia Francesca Lopez, was born Saturday and weighed in at 6 pounds, 4 ounces, "Extra" said on its Web site.
