Many a follower has been lost on Twitter by someone dropping an unexpected spoiler for a popular TV series or movie, but something tells us The Walking Dead’s Norman Reedus won’t be losing any of his nearly half-million followers, even though his bosses might be a little peeved. Reedus plays the one character on The Walking Dead that even the producers wouldn’t dare kill off, so we’re pretty sure he might be the one guy on Twitter who gets a pass for dropping a major spoiler.

Surprisingly, Reedus didn’t drop a spoiler for The Walking Dead, but instead he dropped a spoiler for the Game Of Thrones. Really, most people should have seen the episode by now, since it aired three days ago and has been all over the Internet, but just in case be warned that spoilers follow.

Earlier today, Reedus tweeted, “game of thrones I caught up why u gotta kill off the wolves !!?? dragon lady burn those lions up!!!!” Even though Norman Reedus had caught up on his viewing, apparently Walking Dead showrunner Scott M. Gimple was still running behind. Scott M. Gimple tweeted, “CORRECTION: I think I just got Game of Thrones spoiled by @wwwbigbaldhead, which feels so meta that my mind has fallen through time.”

Reedus quickly apologized, tweeting back, “@ScottMGimple Oh man sorry boss. bring on the dragon.” Walking Dead creator Robert Kirkman also jumped into the fray, admonishing both Reedus and Gimple. Kirkman tweeted, “@ScottMGimple @wwwbigbaldhead Stay off the Internet, Scott! And damn it, Norman! You should know better!”

So we’ve got to ask, since Norman Reedus has tweeted a Game Of Thrones spoiler, does this mean that the Game Of Thrones cast will start tweeting Walking Dead spoilers?
