Keegan in plot revealing twitter blunder

Michelle Keegan revealed a major 'Coronation Street' plot after accidentally posting a snap on Twitter.

The 26-year-old actress - who plays Tina McIntyre in the ITV soap - has caused outrage among fans after she uploaded a picture on the social networking site of her co-star Jack P Shepherd, smoking a shisha pipe, but she had failed to realise that she'd caught two scripts in the shot as well.
