The pop singer turned down a relatively major role because as she said in involved “too much incest”. “I felt uncomfortable because I would have had to go on a horse and he would have touched me up and shit. Once they told me what was entailed, I said no thanks.”
It is true that the incestinal scenes take place before Theon realizes Yara is his sister, but Allen drew the line and also disclosed that some of her brother’s scenes are “very difficult to watch”.
