The Weatherfield actress believes that her character's turbulent love life is crucial to her popularity.
"I don't think I'd like to have a wedding," she told this week's TV Times. "I like Michelle on her own; it's more interesting."
Michelle, who was previously engaged to Ciaran McCarthy (Keith Duffy), soon rekindles her romance with Steve McDonald (Simon Gregson), with whom she once lived in the Rovers Return.
"It is nice to work with Simon again," Marsh added. "We were chuffed when we found out because we enjoyed working together."
Speaking to Digital Spy last month, the star renewed her call for the return of ex-fiancé Ciaran, and hinted at a "spark" between Michelle and newcomer Rob (Marc Baylis).
