UPDATE (6/2): The singer's brother has a different story. Read his account of Lily's Game of Thrones involvement right here.

Was Lily Allen headed for Westeros? Almost, but not quite. 

As MTV points out, the British pop star revealed in a Reddit AMA that she was approached for a cameo in the massively popular HBO series Game of Thrones, where her real-life brother Alfie Allen currently stars as Theon Greyjoy. But ultimately, she had to pass. 

“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 [my brother] would have touched me up and sh-t," she wrote. "Once they told me what was entailed, I said no thanks.”

The scene Allen is talking about has already aired with another actress playing the character. One Reddit user wrote, "There was so much sexual tension in that scene, made me so uncomfortable watching. No wonder she passed it up," to which Allen replied, "Agreed."

Allen also spilled a few more candid gems during the session, talking about masturbating when she's alone, why GZA is the best Wu-Tang lyricist and saying Sky Ferreira deserves more radio play. 

There's still hope though for some sort of Game of Thrones meets Sheezus collaboration. "I would be open to doing a musical cameo like Sigur Ros, though."
