The 29-year-old actress - who plays Daenerys Targaryen in the award-winning HBO series - had no problems stripping off for a scene aired in the most recent episode, which sees her emerge from a sea of flames with no clothes on.
She told Entertainment Weekly: "I'd like to remind people the last time I took my clothes off was season 3.
"That was a while ago. It's now season 6. But this is all me, all proud, all strong. I'm just feeling genuinely happy I said, 'Yes.' That ain't no body double. It's so exciting, very tingly-making. Every season I get at least one spine-chilling moment."
Meanwhile, Emilia previously revealed she has a specific way to get into character for her role in Game of Thrones - by listening to "gangster rap".
She said: "A lot of gangster rap before Thrones. So Tupac. Biggie. But then some Florence. And Beyonce obviously.
"I tried Eminem once, but that was too much. For me, it's like, you wake up and think, 'I'm not feeling particularly badass this morning. Coolio, Biggie, can you help me?'
"When you're doing a huge scene, trying to empower hundreds of extras, you've got to get me to a G."
And whilst Emilia is used to playing strong female characters in her various roles, she previously admitted she is "winging it".
She said: "Of the strong women I play, I'm winging it! I read it [Jojo Moyes' bestselling novel on which the film Me Before You is based] and it just ... literally from the first chapter I was like, 'This is me! Oh my god, I've got to do it! Genuinely, never in my life, have I wanted a part more than this. The closest parallel I have is Bridget Jones, in essence.
"Doesn't quite think much of herself, doesn't think before she speaks, doesn't think before she acts, tends to fall and knock things over ... She just has a huge presence and a huge amount of energy and a lot of crazy thoughts running around her rather bonkers mind."
