John Barrowman says Jacqueline Jossa transforms from Queen of the Jungle to "queen of the night" on 'All Star Musicals'.
The ITV show's host has teased fans they can expect a big performance from the 'I'm A Celebrity... Get Me Out Of Here!' winner in the second episode of the series, which airs on April 3rd.
He said: "Jacqueline Jossa – the Queen of the jungle, let’s just say she becomes the queen of the night in her performance – she is regal and elegant and surprises everybody because who knew she could sing?!"
As well as Jacqueline, Good Morning Britain's Alex Beresford, wildlife presenter Michaela Strachan, Coronation Street's Lisa George, James Bond actor Colin Salmon and rugby star Danny Care will also be flexing their musical muscles in the episode.
John added: "The second instalment is going to be a roller-coaster whirlwind ride of big performances, subtle performances but all of them you need to know will entail singing, dancing and acting.
"We get to see who is a real triple threat in this show, and some who are only a double threat!
"We have a great range of people. Without giving away who is doing what, we have a big number from Les Misérables, we have a big number from 42nd Street, we have also got a number from Chicago. Right there – there’s 3 big production numbers!"
Speaking about what can be expected from the series, judge Samantha Barks said: "So this series is going to be amazing because every single series I feel like the stakes get higher.
"The celebrities see someone they know or their friends giving it a go and doing really well and they want to do better and better and better because they've seen everyone else do it.
"One told me in particular that they saw it and said I really want to do this, this is what I want to do, I want to give it a go and were on the fence about doing it.
"They’ve plucked up the courage to come and do it now which is really cool."
'All Star Musicals' airs 3rd April, 7:30pm on ITV and ITV Hub
