Lisa Robin Kelly (†2013) was a main member of the hit show That '70s Show as "Laurie Foreman", "Eric's" cruel older sister. The two had the best dynamic and incredibly hilarious repertoire. Lisa, unfortunately, struggled with newfound fame and turned to alcohol and drugs so her character was re-cast.

For one season Lisa Robin Kelly was written off the show but returned for season 5, which would be her final season as part of the cast. In season 6, Christina Moore was cast in place of Lisa, and the scenes were re-shot with Christine due to Lisa leaving for personal issues. Tragically the beautiful star passed away due to an overdose after a rollercoaster few years filled with DUIs, arrests, and addiction.
