Fans of the show know that Robert has been leading a double life being engaged to both Michelle and Vicky, who is pregnant with his child.
However Michelle soon found out what Robert had been up to when she followed him to Vicky's house and saw the couple arguing.
She later confronted her fiancé and he told her that he and Vicky had a one-night stand when he and Michelle weren't together leading to Vicky getting pregnant.
But when Michelle talked to Vicky, she told her the truth - she was also engaged to Robert.
Despite Michelle telling Robert she believed his version of events, she has been secretly plotting revenge by trying to take him for every penny he's got.
But viewers don't think she's plotting alone...
In last night's episode of Corrie (December 2 2019), Robert and Michelle told their family that Robert's upcoming 50th birthday celebration was really their wedding.
I think Michelle and Vicky are working together to get revenge on Robert.
But the gathering was soon gatecrashed by Vicky, who also threatened to take Robert to the cleaners.
Michelle quickly suggested to Robert they put the Bistro completely in her name to stop Vicky getting her hands on it and in a matter of hours she had the paperwork drawn up.
But when Michelle told her soon-to-be husband that she was worried Vicky would gatecrash their wedding, Robert went round to Vicky's house.
The neighbour soon heard a loud scream, leading viewers to believe that he has possibly killed her.
But some viewers think that Michelle and Vicky are working together to get their revenge on the cheater.
As Michelle and Robert make it to the church later this week, will they actually say I do?
Or will Michelle's plan take a very dark turn indeed?
Coronation Street airs on Mondays, Wednesdays and Fridays at 7.30pm and 8.30pm on ITV.
