A Houston couple received a double Valentine's gift when Tressa and Manuel Montalvo welcomed not one set of twins but two.

While technically not quadruplets as; Ace, Blaine, Cash and Dylan are two sets of identical twins, their births are still remarkable with chances of just one in 70 million as they were born without IVF.

All boys and all healthy and weighing between 3 pounds 15 ounces and 2 pounds 15 ounces each, they are all still in the neonatal intensive care unit at the Women's Hospital of Texas.

Tressa and Manuel only wanted a sibling for their 2 year old son Memphis but are already getting used to the idea of a big family.

But this is more than a home run. Ace was born first. Then Blaine. They are identical twins. Then came Cash and Dylan. They are a second set of identical twins.
