Most people would not turn down a role on "Game of Thrones," but Lily Allen has good reason! The British singer would not make a cameo in HBO's hit series because it would require sex scenes with real-life brother, Alfie Allen. Makes sense to us!

"I felt uncomfortable," Allen said during a Reddit AMA. "Because I would have had to go on a horse and he would have touched me up and sh--. Once they told me what was entailed, I said no thanks."

Us Weekly said the episode, titled "The Night Remembers," aired in season two. The role was Yara, played by Gemma Whelan. Allen's character, Theon Greyjoy, gets handsy with the woman while horseback riding, and eventually realizes Yara is his sister.
