Jacqueline has been on maternity leave after welcoming her daughter Ella in February, but fans will be pleased to see her back on the soap as Lauren for a brief stint.
Lauren will return to Albert Square for her dad Max's trial, as he's being accused of killing Lucy Beale, only Lauren knows that Lucy's younger brother Bobby is the real culprit.
Viewers last saw Lauren on screen in February, as she left Walford with boyfriend Peter Beale to start a new life in New Zealand with their soon-to-be new arrival, as Lauren was also pregnant.
Peter had confided in Lauren about the truth behind Lucy's murder, which was one of the main reasons why they decided to leave the Square.
But now with Lauren's sister Abi preparing to give evidence against their dad in court, will Lauren reveal the truth?
When making her way back to Walford, Lauren is determined to see justice for her dad, but her mind soon turns to other things when she gives birth!
Her waters break while visiting Peter's step-mum Jane Beale, and it's not long before she ends up in hospital, later giving birth to a baby boy named Louie.
Fans will have to tune in to see whether Lauren's surprise return will change the outcome of Max's trial.
See Lauren's return on 14 September at 7.30pm on BBC One.
