UPDATE: HBO says Lily Allen was never offered a role on Game of Thrones.
Safe to say this is one acting opportunity Lily Allen does not regret turning down.
The 29-year-old singer recently revealed, via a Reddit Ask Me Anything chat, that she was offered a cameo on the hit series Game of Thrones alongside her brother Alfie Allen, who plays Theon Greyjoy on the hit HBO show.
However, the brunette beauty turned down the role because it involved an incestuous scene in which Allen would have been felt up by her real-life brother.
Allen explained, "I've been asked to do a Game of Thrones cameo, 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 s--t. Once they told me what was entailed, I said no thanks. I would be open to doing a musical cameo like Sigur Rós, though."
In the season-two episode "The Night Remembers," Greyjoy meets a woman who he hasn't seen in years, and while the two are riding horseback, he intimately caresses her, only to later find out that she is his sister.
The part of Yara Greyjoy instead went to actress Gemma Whelan, who also appeared in last week's show.
While Lily is concentrating on her music career, having recently released her new album Sheezus, her brother continues to star on the hit series, and recently opened up to Entertainment Weekly about the forthcoming episodes.
"It gets dark," he said. "I don't think people will find it as hard to watch this year. It depends what kind of person you are. It's more of a mental torture than it is physical. It's daunting as an actor. I have to do more telling of the story with my eyes than with words. I've never really done that type before."
