Viewers have been gripped by a plot surrounding who the father of Kylie Platt's baby is after she had a one-night stand with brother-in-law Nick Tilsley.
Kylie's husband David takes a paternity test to find out if he's the dad - and Michelle, 26, accidentally revealed the result by Tweeting a picture of her scripts.
The snap, showing co-star Jack P Shepherd smoking a shisha pipe in a Manchester café, clearly shows the papers on the table.
It's thought that the actors were discussing the big scene during a break from filming.
‘She obviously didn't do it on purpose,' a source tells The Sun, 'but she faces a major dressing down.'
It's not the first time Michelle has been involved in an embarrassing social media gaffe.
She blamed a pal for hacking her account and posting the saucy snap.
