When Tina and Peter are alone together, temptation gains the upper hand (© ITV)
After he kissed Tina at his wedding to Carla, Peter decided to distance himself from the young barmaid and spend his time trying to overcome the guilt he feels for cheating on his new wife.
But in behind-the-scenes footage Michelle explained that Tina has other ideas.
"Things are really heating up between Tina and Peter this week, heating up big time," she said.
"In the past few weeks we have seen Peter wanting nothing to do with Tina and he shuns her saying he wants to focus on the wedding and his marriage (to Carla) so Tina backs off, but she has a cunning plan.
"Her plan is to try and make him jealous to see that he still cares and in that way she has had to flirt with Rob (Donovan).
"Peter doesn't like what is happening between Rob and Tina and he actually warns Rob off her, as if he can even have a say."
Emotions are running very high at the minute and they just can't help the way they feel.

But as an angry Tina decides to confront Peter about his actions, they end up in bed together.
Michelle revealed: "After they do eventually get together Tina is straight away emotionally attached and she believes Peter will leave Carla for her and they will become an item.
"But in Peter's head he actually does feel guilty and I think he does regret it.
"I think what Peter has done is dashed her hopes and he has sort of brought her up to bring her down again and Tina gets really angry and feels let down by Peter."
Eventually their secret is uncovered by Rovers landlady Liz McDonald who decides to take matters into her own hands to protect her employee.
"Liz reacts in a very angry way, she starts blaming Peter saying that Tina has been taken advantage of.
"So with Liz knowing and Tina becoming more emotional does that mean the secret is going to finally come out? You'll have to wait and see."
Monday's hour long episode of Coronation Street starts at 7pm on UTV.
