EastEnders and Coronation Street fans will have to make a big decision tonight - as the soap's are going head-to-head.
In a major shake-up to the schedule, Corrie will air a special hour-long helping of Weatherfield action.
Rather than having two separate episodes at 7.30pm and 8.30pm - viewers will get to watch the whole episode in one go.
However, this does mean that there will be a clash when EastEnders starts at the regular time of 8pm.
Corrie made a blunder on their Twitter page while posting a preview clip from Monday night's episode.
They tweeted: "TONIGHT AT 7.30 & 8.30PM. While visiting David in prison, he tells Shona the possible reason for Max's recent bad behaviour. How will Shona feel when she finds out?"
One Corrie fan asked if the 'heat' had got to the social team as the show is an hour-long special tonight.
Seeing the funny side, the Corrie account replied: "Oops!"
On tonight's Corrie, David reveals that it was Kylie's birthday last week, which may have prompted Max's troubling behaviour.
Will she be able to make amends with Max?
Down in Walford, Mel is trying to keep Hunter alive while covering her tracks.
Previewing the episode, EastEnders tweeted: "When Ben wants something, he normally finds a way to get it. #EastEnders. Tonight. 8pm.
Ben tells Mel that he wants help finding Lisa, but she has something else which is much more important on her mind.
Will anyone realise Hunter is back in Albert Square?
*EastEnders airs tonight on BBC One at 8pm and Coronation Street airs tonight on ITV at 7.30pm
