But Lauren is BACK – and she's on a mission to save dad Max from going down for Lucy Beale's murder.
However, in typical EastEnders fashion, Lauren's return doesn't quite go to plan and she ends up giving birth to little boy Louie.
Among those at the hospital with the proud new mum, played by Jacqueline Jossa, is Jane Beale.
Jane may be all smiles as she cradles her new grandson, but she's undoubtedly very aware of the fact Lauren knows the truth about Lucy's death.
Before her departure, Lauren insisted she would keep the Beales' secret – and not reveal that their youngest son Bobby is responsible for killing his sister.
However that was before her own father was facing being sent to prison for a crime he didn't commit.
Unfortunately Lauren wont' be sticking around for too long, as Jacqueline is still on maternity leave following the birth of her and Dan Osborne's adorable little girl Ella.
Will Lauren break her promise in order to save Max? Viewers will have to wait until 17 September to find out!
