Full principal casting has been announced for I Can't Sing! The X Factor Musical, which premieres at the London Palladium in March.
As previously announced, WhatsOnStage Award-winner Nigel Harman will play X Factor supremo Simon, with Cynthia Erivo, currently nominated for a WhatsOnStage Award for The Color Purple, and Alan Morrissey as lovestruck contestants Chenice and Max.
Erivo and Harman both took part in Friday's launch of the 2014 WhatsOnStage Awards - click here to watch video highlights.
Hill said of the casting, "I'm thrilled with the acting company we have on board - and it's a coup to have Nigel Harman as Simon. He was so funny in Shrek the Musical - not so much in Downton. With the wig and teeth he looks more like Simon, than Simon."
The cast performed a medley of the songs from I Can't Sing! The X Factor Musical during this year's Royal Variety Performance, which will be broadcast on ITV1 tonight (9 December) from 7.30pm.
