David’s admission is the first official confirmation from the singer’s family.
"Yes, twins,” he told the Spanish language TV show, People reported. “The thing is in my family, my sister also had twins, so it's a hereditary thing," he said.
And he already has gifts for the impending arrivals.
"In Puerto Rico it's custom to buy an azabache [jet black, stone] bracelet for babies to protect them from the evil eye, it's part of our culture," he said.
The elder Lopez said he was thrilled for his daughter.
"I'm very proud,” David said. “Jennifer has yearned to be a mother for many years.”
