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.

Mariska Hargitay was 3 years old when her mother, actress Jayne Mansfield, was killed in a car accident in 1967. The mother of five, who was compared to Marilyn Monroe, was 34.

Mariska looked sensational as she channeled old Hollywood glamour in a dark pink and black sequin gown with a black silk Bardot neckline. Her daughter Amaya twinned with her in a sparkling black dress, and her sons, as well as her husband.
