“We adopted Amaya, and Andrew, I always describe it as this angel that fell out of the sky, because he was a little unexpected,” the actress continues.

The decision to add two more children to their family, while surprising at first, was apivotal moment in the pair’s marriage, and for the better.

“It’s something that happened very quickly, when adoption can take a long time,” Hargitay adds. “We were so beautifully and surprisingly … not because we’re not in sync, but surprisingly in sync about something so huge. So momentous.”
