Lena Headey made an appearance on "Jimmy Kimmel Live" Monday night after the "Game of Thrones" season four finale and had something to say about spoilers.

Those who follow Headey on Instagram have seen what many believed to be a tease for Lady Stoneheart's appearance in the series. Headey posted an image of stones in a shape of a heart, which many fans took a wink to what was to come in the series.

Kimmel asked Headey about her alleged Instagram spoilers, according to ComicBook.com. The late night show host asked Headey if she had permission to put up an image of her thumbs pressed up on Pedro Pascal's eyes weeks before his character would die this way. Headey said no, but joked the decision could cost her job.

Next Kimmel held up the infamous "Lady Stoneheart" photo from her Instagram. Headey claims she didn't mean anything by the image and took the photo because she thought it looked cool.

"Because I saw this that you posted on your Instagram also, which everyone thought was a reference to a character from the books," Kimmel said to Headey. "And everyone thought that since you did the last one, this meant Lady Stoneheart...is that the name of the character...was going to be a part of the show. And then that didn't happen."

"No, that was me drunk in Palm Springs going this is so pretty," Headey replied.

However, Headey's outfit choice may be a nod to readers again. The actress wore a black shirt with a heart printed on it that read, "I'm not sorry." The heart could be a reference to the "Lady Stoneheart" picture, but Headey played coy during the Kimmel interview.

The actress also accepted Kimmel's challenge for a wine goblet drink-off with Headey in character as Cersei Lannister. Check it out in the video below.
