Sad news for the cast and crew of Liv and Maddie: the legendary actress Patty Duke, who played Grandma Janice and Great-Aunt Hilary on the show, has passed away. It was extra special when it was announced she would be guest-starring on the show, since Patty starred in her own show in the 1960s, The Patty Duke Show where she played identical twin cousins with opposite personalities, much like Dove Cameron plays on Liv and Maddie. She was only 69 years old but her legacy will live on forever.
Some of the shows stars have taken to Instagram and Twitter to pay tribute to Patty. Click through the gallery to see their posts and feel free to leave your condolences in the comments section below.
