Jared Padalecki says he wasn’t informed of his Supernatural co-star Jensen Ackles’ new prequel show, The Winchesters, and isn’t taking the news well.

Padalecki and Ackles played brothers Sam and Dean Winchester in the long-running series, which ran for 15 seasons before its shocking finale last November. On Thursday, 43-year-old Ackles tweeted a link to a Deadline article reporting that he and his wife, Danneel, are executive producing a prequel focusing on Sam and Dean Winchester’s parents that’s currently in development at the CW.

But 38-year-old Padalecki tweeted on Thursday that nobody informed him of the prequel. The actor shared Ackles’ tweet, writing, “Dude. Happy for you. Wish I heard about this some way other than Twitter. I’m excited to watch, but bummed that Sam Winchester had no involvement whatsoever.”

He later replied to a fan who tweeted, “this has GOTTA be a bad joke hello @jarpad @JensenAckles this ain’t it sirs we’re freaking out.” Padalecki confirmed he was serious, writing, “No. It’s not. This is the first I’ve heard about it. I’m gutted.”
