Mariska Hargitay has dropped a bombshell family secret in her new film "My Mom Jayne" at its premiere at the Cannes Film Festival. The "Law and Order" actress, who is the daughter of the late Hollywood sex symbol Jayne Mansfield, revealed a secret she has been sitting on for decades. In her directorial debut, she shared with audiences for the first time that her biological father was not in fact Mickey Hargitay, the Hungarian bodybuilding champion-turned-actor who wed her mother in 1956.
