Mariska Hargitay revealed in a new documentary that her biological father is not Mickey Hargitay, the man who raised her, but rather singer Nelson Sardelli.

Jayne Mansfield died tragically in an auto accident in 1967.

Mariska described learning the truth about her parentage as feeling like "the floor fell out from underneath me," like she was "living a lie" and as though her "infrastructure was dissolved."
