Natalie Cassidy is to reprise her role as Sonia Fowler in EastEnders in January.
Warning: spoiler alert!
Sonia will return to Albert Square with daughter Rebecca in what the BBC has described as a "gripping storyline" involving the women of the Butcher household.
Cassidy left the soap as a regular cast member seven years ago but has made guest appearances in the interim.
Commenting on her return, she said: "I feel so lucky as an actress to get back to my roots.
"It's such an exciting time for the show - I cannot wait to work with Patsy [Palmer, who plays Bianca] and Lindsey [Coulson, who plays Carol] again. Bring it on."
