The Walking Dead's Robert Kirkman says **** was killed off in the season 6 finale.

The Walking Dead Spoiler Alert

The Walking Dead creator Robert Kirkman is probably one of the few people in the world that knows what happened in the season 7 finale and who Negan killed off in the final seconds of the episode. And as an executive producer on the show, he knows where the show is headed, even if it's in a different direction than the comics.

Kirkman recently appeared on Chris Hardwick's TV show @midnight and joked about the season finale and how the show's episode went viral. That's when Kirkman revealed the following:

“On the next exciting episode of ‘The Walking Dead,' we find out how mad fans are when they learn Negan killed Carl in the Season 6 cliffhanger.”

In the comic books, Glenn, is killed by Negan in the scene. However, the TV show does deviate from the comic books a large percentage of the time. But, it's hard to tell if Robert Kirkman is joking or if he just gave away the biggest spoiler in TV history. In fact, he recently answered a fan question at the Hawaii Comic Con, saying every character on the show will eventually get killed off.

Watch the full episode of last night's @Midnight to hear it from Kirkman himself and decide whether you think there's any truth in his joke.
