Lily Allen revealed during her Reddit AMA ("Ask Me Anything") on Wednesday that she was previously offered a guest role on HBO's Game of Thrones. But she turned it down.

According to the singer, "they asked me if I'd be interested in playing Theon's (played by real-life brother Alfie Allen) sister, and 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. I would be open to doing a musical cameo like Sigur Ros, though."

Incest is hardly new on the hit HBO series, so it isn't surprising that the show would approach Allen about such a scene.
