Devastation street: A furious Tyrone Dobbs (Alan Halsall) confronts best friend Kevin Webster (Michael Le Vell) after finding out truth behind Jack's paternity

Just a week after his wife Molly was killed on the day she left him, grieving Tyrone Dobbs' world is set to be rocked even further.

The naive mechanic is further devastated at Molly's funeral when he discovers his best friend and business partner Kevin Webster is the biological father of her baby Jack.

Tyrone (Alan Halsall) had only just discovered the young tot wasn't his when Molly (Vicky Binns) walked out on him, before dying hours later after getting caught up in the tram crash.

In tonight's episode of Coronation Street, the truth behind the paternity of three-month-old Jack is finally revealed when Tyrone spots Kevin arguing with his estranged wife Sally Webster (Sally Dynevor) in the graveyard.

It finally dawns on Tyrone that Kevin was the mystery man Molly admitted to having an affair with last year.

Stunned by the double betrayal of his wife and best friend, a furious Tyrone attacks a stunned Kevin by the graveside watched by horrified mourners.

Corrie fans saw a fatally-injured Molly confess her affair with Kevin to Sally in the ruins of the Corner Shop in last week's live episode.

A shocked Sally then confronted her husband at their home at 4 Coronation Street and tell him their marriage is over.

Despite her personal torment, Sally declined to tell Tyrone the truth because he was already struggling to deal with his wife's death.

Molly and Kevin's six month affair came to an end last Christmas when the latter found out his wife Sally been diagnosed with breast cancer.

After baby Jack was born in September, Kevin finally found out he was the baby's father last month after sneakily arranging a DNA test without Molly's knowledge.

But after trying to play happy families with Tyrone, Molly told Kevin she was still in love with him and asked them to run away together - but he insisted he still love Sally.

Tyrone's realisation will be screened tonight at 7.30 and 8.30pm on ITV1.
