Tressa Montalvo gave birth to two sets of identical twins on the same day, so four kids at once! "TODAY" spoke with the couple, who said it was definitely a shock. "Good Morning America" reports the two sets of twins grew in two separate placentas. The odds were especially low because Manuel and Tressa Montalvo didn't use in vitro or fertility drugs. The odds of the two sets of twins is 1 in 70 million. HLN reports the children's names will be Ace, Blaine, Cash and Dylan.
