SHOCKED Ken Barlow will catch his son's future wife Leanne Battersby romping with ex-hubby Nick Tilsley.
Ken (played by Bill Roache) threatens to tell bookie son Peter - and it looks like the Corrie wedding could be off.
The pair, left, get close after Leanne (Jane Danson) is taken on as bar manager at The Joinery by first love Nick (Ben Price).
A source told TV Biz: "Leanne is wracked with guilt over the affair.
She loves Peter, she loves his son Simon and they've been through a lot together - but Nick was her first love and she never got over that."
However, Peter (Chris Gascoyne) is not perfect either.
He had an affair earlier this year and committed bigamy the last time he got hitched.
Our source said: "Ken knows Peter is no angel, but blood is thicker than water and his loyalty is to Peter.
"He's worried for his son and for little Simon.
"Leanne regrets her affair with Nick, but there is a chance if Ken doesn't blab, Nick will."
