For the first details on Stella's arrival, make sure to read the main interview with Michelle and her screen partner John Michie.
Read on here, though, for a bonus chat with Michelle - focusing on life at The Rovers and more!
How have you found pulling pints at The Rovers?
"I think my first pint was a pretty good pint! I haven't worked behind a bar for years. I did work behind the bar years ago at The Vic on EastEnders, and I have worked in pubs myself when I was a young actress, so it doesn't really bother me. I remembered how to do it and it was a bit like riding a bike."
There's been some really iconic characters behind the bar at The Rovers, so how does it feel to be following in their footsteps?
"It's nice to be part of it - they've all been great and amazingly strong women. Liz McDonald and Natalie Barnes are two of my favourites. It's big shoes to fill, but we're not all playing the same character. You've just got to take it bit by bit. The scripts have been good, Stella has got a nice storyline, and I like the way it's going. As long as I get good, strong storylines and I can do what I'm paid to do, which is to act, I don't mind."
"She won't be glamorous all the time - she works behind the bar and she doesn't have that much money. She's quite down-to-earth and she's probably not as glamorous as Liz McDonald. You won't see any leopardskin on me! I think she'll just be a different sort of person to have behind the bar - perhaps more subtle, in a way."
What is Stella's fashion sense like?
"She's not a big, bouncy barmaid - she's slightly more subtle. She's a feminine, strong and forthright woman in her late 40s, and as with many women like that, she wants to look smart but dress her age. She doesn't dress inappropriately and her skirts aren't too short, but she does want to be sexy-looking."
Has it been tricky to master a northern accent for the role?
"It's not hugely difficult - it's not like I've been asked to do Geordie or Scottish. It's okay and I have been seeing a dialect coach. I'm surrounded by northerners as well, which helps! There'll always be people who say, 'Oh, her accent's not right, that's not very good', but as time goes on, hopefully people will accept me and accept that my accent is okay."
Do you think the world of soap has changed much since you made your EastEnders departure?
"I left EastEnders when they were doing three episodes a week, working five days a week. Here they do five episodes a week, but they still work five days a week! So the speed is quite incredible - you could have 15 different episodes that you're doing at one time. I don't think people give actors in soap enough credit for how hard they work and the quality of work that's delivered in such a short time."
Finally, have any EastEnders stars been in touch to congratulate you over the new role?
"There aren't that many people at EastEnders now who were there when I was there - there's only really Adam Woodyatt and June Brown. I've had a few texts from people - Adam's been in touch, and Barbara Windsor also sent me a message to say congratulations. Sid Owen did too. So the ones that I worked with have been in touch and they've all been very nice about it!"
