CORONATION Street has signed a Shameless legend for a new storyline – and her first scenes have already aired.

The ITV soap has snapped up actress Rebecca Atkinson for a short-stint on the cobbles playing a prison officer called Mandy.

A hostage situation unfolds in a room with tables and chairs. — Rebecca Atkinson has joined Coronation Street for a short stint

Rebecca played Karen Maguire in Channel 4 show Shameless

She played Karen Maguire in Channel 4 show Shameless betwen 2004 and 2013.

Shock scenes this week saw her make her debut as she was held hostage by Mason Radcliffe’s brother in prison.

Mandy clashed with killer Matty Radcliffe when he refused to leave the visiting area.

As she tried to remove him from the area, he pulled a knife and took her hostage.

She was trapped with cobbles killer Rob Donovan and his son Bobby who was trying to convince his dad to donate a kidney to his sister Carla.

And it appears Rob has turned over a new leaf after finding God.

He tried to talk Matty down but only convinced him to throw Mandy at him before grabbing Bobby instead.

Rob failed to talk him down with words so instead used violence and stopped Bobby from being killed.

And Mandy’s set to return for more episodes in the coming months.

A source said: “Rebecca is a hugely talented actress and she’s a great addition to the cast.

“She’s joined for a short stint and will be on screen for a few months while the storyline she’s involved with plays out.”
