For a brief period, Hamilton was married to the man that helped turn her into Sarah Connor: Terminator director James Cameron. After Cameron split with his third wife, director Kathryn Bigelow, he and Hamilton connected; in 1993, she gave birth to their daughter, Josephine, and from 1997 to 1999, the two were officially husband and wife.

As Hamilton explained to The Daily Mail, James Cameron wasn't someone who could easily settle down. "The woman he can't get is always his dream girl," Hamilton explained. "Work and women go hand in hand for Jimbo, and I should know." Cameron and Hamilton split when he fell in love with actress and model-turned-environmental advocate Suzi Amis, who he met on the set of Titanic, resulting in a $50 million divorce settlement.
