Cindy Williams is mourning the passing of her friend Penny Marshall. Williams played Shirley, opposite Marshall's Lavern on the classic TV show, “Laverne and Shirley.” Their show was a huge hit when it debuted in 1976. “What an extraordinary loss," Williams said in a statement. “My good friend, Penny Marshall is gone, one in a million. Oh what fun we had. Can't describe how I’ll miss her." Inside Edition spoke to Williams in 2015 about their time together, which wasn't always smooth.
