After a record-breaking run, The CW's Supernatural will come to a close with Season 15. Stars Jensen Ackles, Jared Padalecki and Misha Collins announced the news in a video on Twitter.

"We have some big news that we wanted y'all to hear from us," Padalecki said.

"We just told the crew that, though we're very, very excited about moving into our 15th season, it will be our last," Ackles explained. "15 years of a show that has certainly changed my life. I know it's changed these two guys' life. We wanted you to hear from us that, though we're excited about next year, it will be the finale -- the big, grand finale of an institution."

"We've cried some tears and we'll cry some more," Padalecki added with a laugh. "We'll work all the emotion into next season."

"We love you guys, and this family is not going anywhere, even though the show will come to an end," Collins assured.

"A little word from Mr. Eric Kripke, the creator of this world and these characters, that in a show about family, it is amazing and it is the pride of his life that it became family," Ackles concluded. "So thank you guys for that."
