Sophie Turner reveals origin of her shocking new wolf tattoo

Actress Sophie Turner insists the giant new wolf tattoo on her arm has nothing to do with her hit TV show Game Of Thrones.

The 20 year old, who plays Sansa Stark in the HBO series, left fans in shock when she posted a photo of herself on Instagram with the new marking earlier this week (15Aug16), but the stunning star has laughed off the controversy, noting the ink isn't permanent.

"It's not real!" she tells ETOnline at Variety’s Young Hollywood event in Los Angeles on Tuesday (17Aug16).

Turner, who normally dyes her hair red, also debuted a new blonde hairdo in the image, but she assures the golden locks are also temporary.

"And the hair is fake...everything's fake!" she clarified.

Sophie underwent the tattoo and hair transformation for her role in forthcoming independent drama Huntsville, and although she's having fun shooting the movie, she doesn't plan on maintaining her character's style in real life.

"I had more fun as a redhead," she smiles.

While walking the Young Hollywood red carpet, Turner couldn't avoid being asked about what will happen during the next season of Game of Thrones, which she stars in with Kit Harington, who plays her older half-brother Jon Snow.

But before revealing what fans can expect to see in season seven of the fantasy series, Sophie felt compelled to praise her co-star Kit, calling him "one of my best, best friends in the world and my big brother."

"It's such a blast working with him, and we do kinda have that sibling relationship," she gushed. "We tease each other, and he really gets under my skin ... He’s the best, I love him."

She also noted the unique relationship formed between her character Sansa and his persona Jon Snow during the last season is something she never expected to happen.

"It was everything I'd hoped her character would develop into," she said of how Sansa transformed in recent episodes. "It felt very empowering to be able to do that, and play such a strong character... And it was f**king great having my first kill as well."

As for a Stark family reunion, Sophie tells fans not to get their hopes up, pointing out the fact that Game of Thrones is "not really a people-pleaser kind of show."
