Lena Headey reveals she’s as feisty in real life as her Game of Thrones Season 6 character, Cersei Lannister. The actress recently slammed critics of her controversial Walk of Shame in Season 5. Apparently, the actress received flak for using a body double for her nude parade.

Headey revealed in an interview with Entertainment Weekly that people thought that she was less of an actress after opting to have her body double, Rebecca Van Cleave, do the scene in her place. The 42-year-old actress explained that while she has done nudity in the past and is not against it, she was wary that she would get too emotional if she did it.

“I know I’m a very emotional actor and I get really driven by that. In order to do my job, I allow myself to be really vulnerable,” said Headey. “The thought of being naked for three days and trying to contain her in the way she would be I think I would feel very angry. I didn’t want to be angry. I don’t think Cersei would be angry.”

According to Harper’s Bazaar, Headey praised Van Cleave’s performance and for being able to contain her emotions while naked. She also explained that she did not handpick Van Cleave for the role, contrary to critics’ assumption that she “demanded to have a hot body.”

The Walk of Shame may have shaken the powerful Lannister matriarch, but it has not broken her spirit. When asked if it made Cersei nice in Game of Thrones Season 6, she responded that it “worsened things.”

Lena Headey revealed that the walk has not humbled Cersei, and has in fact “fueled her desire and her desperation to prove that she’s somebody worth considering.”

But despite her thirst for vengeance, Headey promised viewers they will see a more vulnerable Cersei.

She narrated that there will be a scene in Game of Thrones Season 6 where Jaime Lannister returns with a dead Myrcella. Contrary to the typical Cersei approach, Jaime’s failure is not met with any screaming or scolding.

“There’s a moment with Jaime where she’s broken and it’s so genuine. It’s purely a mother lamenting the purity of her child,” shared Headey via Entertainment Weekly. “I never thought Cersei would say out loud what’s said in this scene; it was quite a beautiful moment.”

Game of Thrones Season 6, which Headey dubbed as Cersei’s “most interesting season,” will premiere on HBO on April 24.
