Yes, you read that headline right.
In case you weren’t aware, singer Lily Allen’s brother is a series regular on HBO’s "Game of Thrones." Her brother Alfie Allen plays Theon Greyjoy and while incest isn’t an uncommon subject on the medieval fantasy show, it would’ve been way too much for the famous siblings.
During an "Ask Me Anything" session on Reddit, Lily disclosed that she had been asked to do a cameo, but once she learned it would involve actual incest, you can understand why she turned it down.
"I've been asked to do a "Game of Thrones" cameo,” Lily answered, “they asked me if I'd be interested in playing Theon's 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 Rós, though.”
Fans may remember this scene in season two when Theon reunites with a woman he hasn’t seen in years. They get intimate on a horse together, but he becomes embarrassed when he discovers that they're related. Yeeeeeesh.
