Michelle accidentally shows results of David Platt's paternity test

Michelle Keegan was left red-faced yesterday when she accidentally let slip the outcome of a major Coronation Street storyline.

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.

Michelle, who is dating ex-TOWIE star Mark Wright, quickly deleted the shot but it had already been re-Tweeted by many of her 1.3million followers.

‘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.

Earlier this year a picture appeared on her Instagram page of a topless girl – whose head was out of shot – in the bath but the actress denied that they were her boobs.

She blamed a pal for hacking her account and posting the saucy snap.
