Ed Balls posted a Strictly spoiler ahead of last night's results and people weren't happy.
Although Strictly makes out that it's Sunday show is live, the show is in fact pre-recorded on the Saturday night straight after the main show.
And that has often led to spoilers about the Strictly Come Dancing results making their way online.
Last night Ed accidentally angered fans after revealing Anastacia had left in the latest elimination, before it happened on TV.
He posted to his Facebook page: "Thanks so much - I loved being a mad scientist and dancing the Cha Cha - Katya's choreography was truly brilliant. So it's on to the Quick Step - very sadly without the lovely Anastacia...
"Blackpool is still a few weeks away but it would be wonderful for us to go back to where Katya has won so many British and world titles... we'll see, but thanks for everything so far !"
Fans were quick to point out the error and some were angry at the spoiler.
"Someone has forgotten the clocks went back," quipped one commenter on the status.
Ed however was quick to edit the post, removing the spoiler before Anastacia did eventually end up leaving the competition.
Anastacia and her pro partner Brendan Cole were in the bottom two on Sunday night's show alongside model Daisy Lowe and her partner Aljaž Škorjanec.
And in a unanimous vote, the judges decided to save Daisy and sent home Anastacia in last night's Strictly Come Dancing 2016 results.
