EastEnders has announced that there will be a new Mitchell in Albert Square this autumn, Nicola Mitchell - Teddy's ex-wife.
Laura Doddington, who has starred in Doctors, Holby, and The Midwich Cuckoos, will play Nicola and has begun filming.
Teeing up what's ahead, the BBC soap said: "Nicola wastes no time making her presence felt as she introduces herself to the rest of the Mitchells and tries to build bridges with sons Harry and Barney.
"Teddy will be less than impressed to have Nicola invading his new neighbourhood. However, Nicola is determined to stand her ground, whether Teddy likes it or not."
"I still can't believe I've joined EastEnders - I keep pinching myself!" said Doddington.
"I grew up watching the show, so the first time I filmed in The Vic, I was like a kid at Christmas to be in such an iconic place with such a brilliant cast and crew.
"Nicola is a complex woman who comes in like the Tasmanian Devil! She's strong and completely unapologetic about who she is.
"I've been so lucky to have my Mitchell boys, Roland (Manookian, who plays Teddy), Elijah (Holloway, who plays Harry), and Lewis (Bridgeman, who plays Barney), as they've taken me under their wing, and we feel like a family already. I'm loving every second so far."
EastEnders Executive Producer Chris Clenshaw said: "Like all the great Mitchell women, Nicola is feisty, strong, and loves her family.
"She and Teddy share a very complicated history, which will be fun to explore, as will her relationships with her two sons.
"We're delighted to welcome the fantastic Laura Doddington to EastEnders to bring Nicola to life."
EastEnders airs on RTÉ One and BBC One Monday to Thursday.
