The Emmerdale star will play the leading role in Jack And The Beanstalk at Bradford's Alhambra Theatre this Christmas, opposite Ru Paul's Drag Race UK star Divina De Campo and 71-year-old comedian Billy Pearce.
Miller, 31, said: “I have loved the story of Jack and the Beanstalk since I was a kid so I’m really excited to bring it to life on the stage. To get the chance alongside Billy and Divina will be bags of fun!"
The soap star announced the news on Twitter joking: "Oh yes I am!"
Drag Queen De Campo, who was runner-up on the first series of Drag Race UK, said: “I’m so excited to be coming back to the Alhambra theatre and Bradford!
"The Alhambra has a very special place in my heart as it’s the theatre I saw most of my firsts at. I'm tickled green to be bringing my beans with me back home.”
Miller - best known for playing Aaron Dingle in the ITV soap since 2008 - was crowned the winner of ITV reality show I'm A Celebrity in 2021 after pipping fellow soap actor Coronation Street star Simon Gregson in the public vote.
The actor left behind his then six-week-old baby son Albert and fiancee Steph Jones to take part in the reality show at Gwrych Castle in north Wales.
Miller initially struggled to overcome his fear in some of the gruelling trials in the show, and kept being voted by the public to take part in more.
Joking about how he had come across on screen Miller said: "The original idea was to show them that I don't just cry on television but I think I've failed.
"I've played him [Aaron Dingle] for a long time and I wanted show a different side of myself and to have a go at the reality world and I've loved every minute of it."
Miller also enjoyed a bromance with fellow campmate David Ginola, of whom he was a huge fan.
Jack and the Beanstalk runs at the Alhambra from 10 December 2022 to 22 January 2023.
