The actress returns to filming at the Channel 4 soap in January after taking time off for maternity leave.
Waring gave birth to her second daughter Lexi Grace in September. In the same month, fans saw Cindy leave the village for an extended honeymoon after marrying 72-year-old millionaire Alistair.
Writing on Twitter on Friday, Waring revealed: "Eeek got my scripts through this morning! Can't believe how fast my time off has gone! Looking forward to going back!"
The star said that there is "lots of comedy" in store for Cindy, who tied the knot with Alistair for his money alone.
She later added: "Everyone is going to love to hate Cindy! The bitch is back!"
Waring has been part of the Hollyoaks cast on and off since 1996.
