Canadian actress Rhiannon Fish is mourning the loss of her sister. Fish, best known for her role in Australian soap opera Neighbours, is heartbroken following the death of her elder sibling Corinne, who passed away earlier this month (Jul14). The actress, who is now based Down Under, attended a memorial service for Corinne in her native Canada, and shared a number of family pictures on Instagram.com showing herself as a child with her sister. She also added a tribute, writing, "Cory, you were my role model, my hero and without a doubt, the best big sister anyone could ever wish for. I will miss you more than words could possibly begin to describe but I promise I will keep you alive in my heart, every single day, for the rest of my life. I love you. Forever and always. - Your first little sister."
