Earlier this month, Uproxx revealed Headey's spoilerrific Instagram teases.
Most actors have pretty strict confidentiality clauses when it comes to revealing any spoilers in television series/movies, so Headey is straight up trollin’ us.
Pajiba elaborates on the spoiler accusations...
Over on Instagram before the fourth season of Game of Thrones started, Lena Headey had the AUDACITY to spoil two key plot points, although they were only spoiled if you understood the context, and you could only understand the context if you’ve read the books, so they weren’t really spoilers so much as winks toward the future of the series (and one of those spoilers has not come to fruition yet, much to the dismay of book readers).
Vanity Fair explains further...
She’s not responsible for your pain, Lady Stoneheart fans, but she’s also not sorry to have messed with you in the first place. How Cersei of her. Headey went on to record a fun segment with host Jimmy Kimmel where they swigged wine, Lannister-style, and traded Game of Thrones-esque insults.
Lena Headey and Jimmy Kimmel Talk Game of Thrones Style
Lena Headey plays Cersei Lannister on "Game of Thrones". Jimmy is obsessed with the show. He thinks that no one drinks wine like Cersei Lannister - the way she pours, drinks and tosses off insults to whoever happens to be drinking with her. This made Jimmy think that instead of an ordinary interview, it'd be fun for him and Lena to drink wine and talk to each other "Game of Thrones" style.
