The actress, 26, is leaving Weatherfield behind in June when she leaves the soap after six years and moves on to new things - which she says includes having four kids with her TV star fiancé!
Michelle told the Daily Mail's Femail that she's looking forward to a future with Mark and starting a family together.
Revealing she wants four babies, Michelle also told the newspaper: "My mum's told me how exhausting it is but when the time comes I'll be ready."
Michelle and Mark, 27, got engaged last September after a nine-month romance and plan to wed in 2015.
On getting hitched, Michelle says: "The idea of marriage is so appealing and with Mark I knew straight away."
Admitting she has no work lined up after she leaves her role as Tina McIntyre, Michelle also says she'd like to follow in the footsteps of former Corrie stars Suranne Jones and Katherine Kelly by having a varied career.
She reveals: "I'd love to follow suit. I'd like to do a bit of drama, a bit of comedy. Lots of variation, ideally."
Earlier this week, Mark sent another public declaration of love to Michelle on Twitter.
He said: "Having the privilege of saying 'goodnight I love you' to the most special girl in the world every night makes me feel so lucky. #smiling."
Sounds like Mark can't wait to start having little babies, too...
