Most people would not turn down a role on "Game of Thrones," but Lily Allen has good reason! The British singer would not make a cameo in HBO's hit series because it would require sex scenes with real-life brother, Alfie Allen. Makes sense to us!

"I felt uncomfortable," Allen said during a Reddit AMA. "Because I would have had to go on a horse and he would have touched me up and sh--. Once they told me what was entailed, I said no thanks."

Us Weekly said the episode, titled "The Night Remembers," aired in season two. The role was Yara, played by Gemma Whelan. Allen's character, Theon Greyjoy, gets handsy with the woman while horseback riding, and eventually realizes Yara is his sister.

Whelen reprised her character in last week's episode in an attempt to save Greyjoy.

The singer said she would love to, however, play another role on the show.

"I would be open to doing a musical cameo like Sigur Ros," Allen stated.

The songstress' brother told Entertainment Weekly though this season "gets dark" it is not "as hard to watch" as previous seasons.

"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."

Lily is currently focused on her music career and released "Sheezus" on May 5. On Monday, the "Hard Out Here" crooner was seen Monday entering "Today" in New York City. Allen was wearing a sweatshirt with gray pants and popping yellow pumps.

She Instagrammed a close-up selfie from the experience, donning purple eyeliner and pink lipstick.

"Dark circle crew, might barf, #stillill #todayshow," it read.
