Andrew Nicolas Hargitay Hermann is a son of Mariska Hargitay and Peter Hermann. He was adopted by them in October 2011 and got a name in honor of the stars’ friend who had recently died.
Andrew’s adoption was unplanned and Mariska called him an angel that fell out of the sky. Moreover, the process was surprisingly quick.
A curious fact: some sources stated that Andrew was a son of Peter’s friend who died in a car crash and his widow wasn’t able to take care of their newborn son.
