ITVTEASER: Some more details of Carla's return have been released
The Corrie vixen was confirmed to be making a comeback earlier this year after months and months of speculation.
There hasn't yet been much information about the return of Carla Connor – until now, that is.
Corrie boss Kate Oates has revealed a snippet of what's to come, and it seems like it will seriously affect Michelle Connor.
ITVBEEN THERE: Carla slept with Robert while she was engaged to Nick Tilsley
“Their friendship is really strong, so anything that challenges it will have to feel very truthful and quite deep”Kate Oates
Kate told What's On TV: "They have obviously got Robert in common now which is interesting, but their friendship is really strong, so anything that challenges it will have to feel very truthful and quite deep."
Michelle is dating jailbird Robert Preston, though they're faking a split at the moment.
Carla slept with Rob after he returned to Weatherfield to win back his first love Tracy Barlow, despite being engaged to Nick Tilsley.
Producer Kate continued: "I just want to explore the dynamics – [it] would be a shame to leave everything as is. What's good about these long-standing friendships is when you challenge them and see what could potentially break them.
ITVNEW FLAME: Robert is now in a relationship with Michelle
"But that is not the storyline that brings her in, what brings her in is something a bit more unexpected."
Carla was last seen in June 2016, when she moved to Devon alone, leaving both Nick and Robert in Weatherfield.
Michelle will soon realise her ex-boyfriend Will is her stalker and find herself in grave danger.
ITVTENSION: Will things be the same between Carla and Michelle?
But it sounds like she may not have the support of her former best friend Carla due to their shared romantic history.
If Michelle makes it through the rest of the year unscathed, she deserves a star on Weatherfield's walk of fame.
Coronation Street airs Mondays, Wednesdays and Fridays on ITV.
