Coronation Street favourite quits the show and her character could be killed off for good

CORONATION Street star Millie Gibson is quitting the cobbles after three years — and is set to make an “explosive” exit.

Millie, 18, who plays Kelly Neelan, will leave the ITV soap this autumn.

An insider revealed the dramatic storyline could even see wayward teenager Kelly being killed off.

A Corrie source said: “Millie’s a huge talent.

"She has loved her time on the soap but there’s a lot of excitement about what she’s going to do next.

“Everyone has been sworn to secrecy over her exit storyline.

"It’s going to be explosive.

"Millie’s not even telling people if the door has been left open for her.”

Millie was crowned Best Young Performer at the British Soap Awards in June.

Her character featured in a shocking hate crime storyline which saw her convicted of Seb Franklin’s murder but then acquitted after new evidence emerged.

Kelly is unaware Gary Windass killed her loan shark dad Rick.

Her dying mum later Laura confessed to the crime to protect him.

The source said: “Gary’s managed to keep his involvement in the death secret, but it looks like Kelly will finally discover the truth.”
