The former Blind Date host claimed that she has been approached by the ITV1 soap's producers despite turning down the chance to join Weatherfield on a number of occasions in the past.
Black, 66, confirmed that she would like to appear for a one-off episode but is wary of making a greater commitment due to the programme's demanding filming schedule.
Speaking to The Mirror, the star explained: "They have asked me to join the show. It's not their first approach - they have asked me several times. I love Corrie, but I keep saying no.
"I couldn't cope with all the hours they do, they work them like dogs. It's really hard work."
She added: "It would be nice to do a cameo, but even Ian McKellen worked long hours when he did it for a while. If the role was right, I would do a one-off thing."
Black also admitted that she would like to do "more acting" in the future and that a movie role would be "wonderful".
