Singer Lily Allen told her fans on Tuesday that she actually turned down an opportunity to play a key role in Game of Thrones. She really didn’t want to have the hands of her real brother, Alfie Allen, feeling down her dress.

The Sheezus singer said during a Reddit “Ask Me Anything” session that she was offered the role of Theon Greyjoy’s sister. When Theon’s sister is first introduced in the show, Theon, played by Alfie, doesn’t recognize that it’s her sister and starts groping her. When Allen figured that out, she turned the offer down.

“...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,” Allen wrote, notes Billboard. “Once they told me what was entailed, I said no thanks. I would be open to doing a musical cameo like Sigur Ros, though.”

Gemma Whelan took the part of Yara Greyjoy instead.

Alfie also came up in the AMA when a fan asked about the 2007 Alright Still track that she named after her brother. She said that she wouldn’t have released the song if she predicted that she would become famous.

Sheezus comes out on May 6.
