Nastassja Kinski is speaking out in support of her half-sister, Pola Kinski, who recently claimed she was sexually abused by their late father, German actor Klaus Kinski.
"My sister is a heroine, because she has freed her heart, her soul and also her future from the weight of the secret," the actress told German newspaper Bild, BBC News reports.
In her new memoir, Kindermund (Children's Mouths), Pola details how her dad raped her multiple times during a 14-year period. While promoting the book, she recalled that when her mother took up with another man and her parents divorced in 1955, she moved in with her father and traveled with him all over Europe as he worked on his films, which is when the abuse took place.
Added Nastassja, who said she cried upon reading Pola's book, "This is a difficult moment for me. I am on my sister's side, I support her. I am deeply shocked."
She's hopeful that her half-sister's story will help "all the children, adolescents and mothers who fear their father and swallow their fear to hide it in the depths of their souls."
