Laurie Forman – That ’70s Show

Laurie Foreman on That ‘70s Show was Eric’s older sister and his father Red’s favorite child. She was portrayed in seasons one through three and season five by the late Lisa Robin Kelly, and then by Christina Moore for season six.

Moore took over for Kelly after she was fired from the show. Later, Kelly told ABC News that “she was guilty of a drinking problem” and was unfit to continue working on the show at the time.
