The “Hard Out Here” singer was asked to star opposite her brother, Alfie, who plays Theon Greyjoy, she revealed during her “Ask Me Anything” session on Reddit.
Allen was requested to appear as his on-screen sister, Yara, but she was put off by what they explained about the scene.
“I felt uncomfortable because I would have had to go on a horse and he would have touched me up and s**t,” she said. “Once they told me what was entailed I said no thanks.”
The 29-year-old was approached for season two episode, “The Night Remembers”, but her part ended up being played by Gemma Whelan.
In the show, Theon meets a woman from his past and, when they ride a horse together, he fondles her inside and outside her clothes. All this only to learn afterwards that she is his sister – red faces all round.
Allen added that she would be “open to doing a musical cameo, like Sigur Ros”. The Icelandic band covered The National’s “The Rains of Castamere” when they featured as wedding musicians singing for King Joffrey in “The Lion and the Rose” last month.
Coldplay drummer Will Champion and Snow Patrol’s Gary Lightbody have also made cameo appearances on Game of Thrones.
