John Barrowman will be back as presenter of the ITV show, which will feature Elaine Paige, Trevor Dion-Nicholas, and Samantha Barks on the judging panel when the programme returns later this year.

The 'Torchwood' star said: "Now more than ever we're all in need of some fabulous musical entertainment and I can't wait to be reunited with Elaine on stage for 'All Star Musicals'.

"We've got the most amazing show lined up with something for everyone and lots and lots of surprises."

Six celebrities - who have been selected based on their standout performance skills - will be aiming to impress the virtual audience, as well as the panel, by performing an iconic musical number.

The stars will be mentored by Elaine and supported by a West End chorus line, and they will receive training from expert choreographers and vocal coaches in the lead up to their big performance.

Elaine said: "'All Star Musicals' is a joy to be a part of, I'm so pleased to be back heading up the critics panel and mentoring our new celebrities.  

"We've got the most wonderful evening of musical theatre and entertainment lined up for viewers and some very exciting surprises."

Viewers will also be able to see John, Elaine, Trevor and Samantha perform together in the show’s opening number.

Katie Rawcliffe, ITV’s Head of Entertainment Commissioning, said "'All Star Musicals' returns to our screens at a time when we’ve been missing those powerful and thrilling live performances in the theatre.

"This one-off special will be a real celebration of musicals and I can’t wait to see the performances our celebrities deliver on stage."
