JIM McDonald isn't the only ghost from Liz's past who's recently returned to Coronation Street.
Their daughter Katie aka Hannah, who was previously believed dead, has made a shocking return to the Corrie cobbles - but all is not as it seems...
Who is Jim McDonald's 'daughter' Katie on Coronation Street?
Katie McDonald, 26, was born on New Year's Day 1992 after Liz went into labour on New Year's Eve.
Now a woman pretending to be her has returned to Coronation Street with her "dad" Jim McDonald following his release from prison.
Jim was jailed for armed robbery in 2011 and is now trying to scam Liz.
After an emotional reunion with Liz the charade was revealed when Jim said that Katie did him "proud."
She replied: "Hey, less of the old and certainly less of the dad - you're neither."
In a sickening twist it was then revealed that the fake father and daughter are actually lovers!
Katie is played by Australian stage star Hannah Ellis Ryan who has performed in various plays at the Hope Mill Theatre in Manchester.
When did Katie McDonald die?
Liz went into labour on New Year's Eve 1991 after her son Steve went missing.
Katie was born prematurely and was placed in an incubator after doctors said she had little chance of survival - she died the next day on January 2, 1992.
Steve then blamed himself for Katie's death and stayed away from the funeral which was attended by his parents and twin brother Andy.
But in 2018 Jim McDonald arrived back in Weatherfield with Hannah - a girl claiming to be Liz's dead daughter Katie.
The story she gave was that due to a mix-up at the hospital she was adopted by a couple who moved to Australia.
Then when she turned 18 she supposedly tracked down her real father Jim via his military records.
