Lily Allen has revealed that she turned down the chance to play Yara Greyjoy on hit HBO TV show Game of Thrones.
In a Q&A session with Reddit yesterday, the singer admitted that GoT producers had offered her the opportunity to appear alongside her brother, Alfie, who plays Theon Greyjoy in the gore-fuelled series.
But she refused on the grounds that it involved "too much incest".
Lily Allen turned down the opportunity to play Yara Greyjoy
"I've been asked to do a Game of Thrones cameo," the 29-year-old said. "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 shit. Once they told me what was entailed, I said no thanks.
"I would be open to doing a musical cameo like Sigur Ros, though," she added, referring to the Icelandic band's cover of The Rains of Castamere that appeared in an episode of the show (The Lion And The Rose) last month.

Alfie, who is two years younger than his sister, took up the role of Theon in 2011. Lily described him as "a gifted actor".
"I'm very proud," she said.
His character Theon has really had a hard time of it over the past few episodes of GoT, with grisly and extreme scenes of torture hitting our screens on a regular basis.
"I'm finding it very difficult to watch," Lily admitted.

Before he appeared on Game of Thrones , Alfie was best known for appearing in a less-than-flattering light in Lily's song that was named after him on her 2006 debut album.
It contained the (affectionately-meant) lyrics, "My little brother's in his bedroom smoking weed, I tell him he should get up 'cause it's nearly half-past three."
Speaking about her brother's reaction to the song yesterday, Lily said: "I think he was pretty annoyed, understandably, but I didn't know it was going to be as successful as it was at the time of writing. And if I could take it back, I would."

Lily, who has two daughters - Ethel and Marnie - with her husband Sam Cooper, retired from the music industry in 2009. But she made a comeback last year, saying she needed to channel her creativity.
"Why did I choose to come back? I ran out of money!" she told France's NRJ Radio earlier this year. "No, I'm joking! I thought I'd be a really happy mum just sitting at home, playing with my kids, that was my dream.
"I love my children, but I'm a very impatient, busy person naturally so two babies, neither of them can talk, it was quite boring! Staying at home all day talking to people that can't talk back.
"I didn't realise how much of a creative person I am and that I need somewhere to put my creativity."
