She says that she can see herself returning one day and that her former co-stars want her back. She told the paper: "When I left the show I made it clear that I wanted the door to remain open so I'd be able to return. They're always asking me to go back and I think that, one day, I will. I have so many happy memories from working on the Street and I do miss those on the show."
Katherine only left Corrie in January so it may be a bit early yet for her to return but here's hoping it happens one day.
