The storyline sees La Voix invited to perform at the Prince Albert – Walford’s LGBTQ+ bar – but she is tricked into performing at the Queen Vic instead.
She said her nerves in taking part were put at ease when she was reunited with friends Harriet Thorpe, who plays Elaine Peacock, and Michelle Collins, who plays Cindy Beale.
La Voix explained: “It really helped get rid of the nerves because the speed of that filming was relentless.
“I mean, there is no ‘hello, nice to meet everyone, let’s have coffee and chat’, oh, no.
“All of a sudden, I’m standing next to Big Mo and Zoe in the Vic, and I’m like, ‘Oh my god, I’m running lines to camera on EastEnders, this is bonkers!'”
