ENTERTAINMENT: NPH, and partner David Burtka, are Both the Father to The Twins!

Neil Patrick Harris and David Burkta became parents of twins in October.

In case you were wondering whose sperm was used to inseminate the surrogate mother, here is your answer: “We inserted two eggs, one with my sperm, one with David’s sperm and they both took,” he tells People Magazine.

David said holding their children in the delivery room shortly after their birth was “just absolute joy,” says Burtka. “We had two babies that we made. With help.”

“Everyone says that it’s such a blur after it happens,” says Neil says of becoming parents to fraternal twins Harper Grace and Gideon Scott, born Oct. 12 via surrogate. “I find myself constantly just trying to wrap my mind around it.”
