Where did she say she used a body double in the GOT scene?

Thanks, I've read that. It's odd, clearly the article is from and about the body double. The only "sort of" quote from Lena is:

I’ve said from day one that I’ve got no problem with nudity. I’ve done it throughout my career. But for this character, it’s been better for her regality and her feistiness to not bare her flesh until she has to. When it’s out of her control. And if that ever happens, it won’t be Cersei being seductive or sexy. She’ll be stripped. That kind of a scene will have more power if it’s not an everyday occurrence. I can’t wait for that.

But if you read that quote carefully you see she's not talking about that scene or the body double. It's a general quote about her character in the show and the concept of nudity. The key phrase is "and if that ever happens..." that sounds like she was talking to someone way before that scene was even known about. Then she says: "I can't wait for that."

Clearly this quote has nothing to do with the scene or the body double.

I still feel like Lena would never shy away from nudity and never use a body double, especially for that scene.

Is it possible Lena did that scene and that the body double was only used for small parts of it?

That article also talks about how the use of a body double was most likely explained by her pregnancy.

I thought it was pretty obvious. Of course it was very well done, but if you've worked with that kind of effects, there are signs that will tell you that only her head is used for the full body shots.

She has done nude scenes before. If you have seen her body in other movies, you can tell that it's not her body in GoT. I don't know why she used a body double exactly, but she did.

Would you walk naked as an actress infront of hundreds of extras? NO

Odd sh!t to say the least. Damn fine effects then XD
