Another added: "What a brilliant surprise! Anyone else coming back?!"
And a third pleaded: "Can we have Mika return as a regular with her maybe reuniting with Brett? a proper o.g. #waterlooroad reunion."
Lauren was among the original Waterloo Road cast when the school-based drama launched in 2006.

During her stint, Mika was involved in several gritty storylines, including the murder of her mother.
She was bullied by her best friend and even attempted to take her own life as a result.
Mika also turned to alcohol after discovering her boyfriend Brett had slept with her sister Chlo behind her back.
