In what is surely a sign of the actual apocalypse, Supernaturalis officially coming to an end after Season 15 next year.

Jensen Ackles, Jared Padalecki, and Misha Collins shared the news with fans via Twitter today, saying, "Even though we are excited about going into our 15th season, it will be our last. Fifteen years of a show that has certainly changed my life. I know it's changed these two guys' [lives]. We just wanted you to hear it from us. Though we're excited about next year, it will be the finale, the big grand finale of an institution."

"One of my most favorite experiences in front of the camera was getting to kick it with The Winchesters many moons ago. @jarpad @JensenAckles you will be missed!" Sterling K. Brown, who guest-starred on the show in Season 2, tweeted.
