Some fans believe that Lady Stoneheart will not feature at all this season but now, speculation is rife that viewers can expect to see her soon, possibly in the finale.
"Don't Google if you haven't read the books" one Instagram user wrote under Headey's picture. "Lady Stoneheart, confirmed" said another, while one fan wondered "if this counts as spoilers".
Headey's character was the subject of a recent controversial storyline in which she is raped by her twin brother Jamie in front of the corpse of her son, King Joffrey.
But Headey defended the dramatic scene, suggesting that Cersei eventually gave in to her sibling's advances in an attempt to feel something other than grief.
Martin also responded, insisting that while the sex is consensual in his book and the "whole dynamic" is different, it is up to the show's writers to convey it how they wish.
