The actress announced her decision to quit her role as Rovers Return landlady Liz McDonald last October. Press reports have claimed that her final scenes will see Liz bid an emotional farewell to the pub before leaving Weatherfield by herself.
Asked if the door was being left open for a potential return to the ITV1 soap during an appearance on This Morning, Callard said: "I think it is, but we've not actually filmed it yet. I think a lot of the newspapers have run stories about the exit."
She teased: "There's a couple of different versions anyway and so no one really knows yet. I believe I film it next week - either Wednesday or Thursday and so I'm not sure exactly what happens myself, but I don't think she dies."
Speaking about her decision to leave, Callard added: "I needed to take some time off, just for me really. I took some time off last year - they gave me some time.
"Then the new producer Phil Collinson said, 'Come back and shoot this amazing storyline'. When I read the script, I just thought, 'I can't say no to this!'."
