John Barrowman is set to host 'All Star Musicals' alongside Elaine Paige.
The 'I'm A Celebrity... Get Me Out Of Here!' star - who recently stepped in to cover for Phillip Schofield alongside Holly Willoughby on 'This Morning' - will takeover from Freddie Flintoff as the presenter of the ITV special, which sees seven celebrities perform a song from a popular stage show.
Vowing to make the programme "fabulous", the 51-year-old star said: "I can't wait to bring something fabulous to the TV screens, working with new friends and teaming up with some special old friends, this should be a great night of entertainment - let's make 'All Star Musicals' Fabulous."
John - who has starred in many musicals on the West End and Broadway over the years, including 'The Phantom of the Opera', 'Sunset Boulevard' and 'Matador' - will be joined by 70-year-old musical theatre legend Elaine as co-host, who added: "All Star Musicals is the perfect opportunity for me to channel two of my greatest passions - musical theatre and mentoring.
"I'm looking forward to following the celebrities on their journey to performing on London's most prestigious stage, and of course it's an added bonus to have a front row seat on the night itself!"
The celebrities will have a masterclass in theatre, before performing at London's iconic Palladium, where they will be judged by the audience.
The last 'All Star Musicals' special, which aired in 2017, saw the likes of soap stars Lucy Fallon and Michael Parr, and 'Bridget Jones's Diary' actress Sally Phillips compete.
'Coronation' Street' star Lucy - who plays Bethany Platt on the ITV soap - won the festive episode two years ago as she wowed the theatre with her rendition of 'Don't Cry for Me Argentina' from 'Evita'.
The celebrities will have a choice of both contemporary and traditional musicals to pick songs from.
