The first time Sonia Jackson (played by Natalie Cassidy) gave birth back in 2000, she didn't even realise she was pregnant with her daughter, Bex, on EastEnders! (7:30pm - see our TV Guide for listings).
On tonight's special LIVE episode of the BBC soap, screening as part of the 40th Anniversary celebrations, pregnant Sonia is due to give birth again.
However, the circumstances are far from ideal.
Not only is Sonia's killer fiance, Reiss Colwell (Jonny Freeman), the father of her unborn child.
But Sonia finds herself going into labour during explosive events at the Vic during the wedding celebrations of Billy (Perry Fenwick) and Honey Mitchell (Emma Barton).
With no medical support on hand and only two traumatised people close to lend a helping hand, will both Sonia and her baby make it out alive?
