The live episode of EastEnders will be shown on BBC One at 7.30pm tonight, and in the run up to the episode fans have the chance to vote in two polls that will influence the plot.
The names are in honour of the show's creators, Julia Smith and Tony Holland, and fans can choose which name Sonia gives her baby, which will also be included in the live episode.
The episode is being broadcast live from Albert Square, and viewers will get to pick whether Denise Fox (Diane Parish) will reunite with her estranged husband Jack Branning (Scott Maslen) or choose to embark on a new romance with lover Ravi Gulati (Aaron Thiara).
When the live special was announced, Chris Clenshaw, executive producer of the BBC soap, said: “We’re all so excited to give our audience their first ever chance to decide how one of our big storylines plays out.
“I think Sonia and Bianca will be with the baby and when the Vic is rebuilt they will both leave and rent Dot’s house to Lauren to keep it in the faammmlee,” was the detailed prediction of one viewer, who may only have to wait until later tonight to find out if they were right.
