Premiere for X Factor spoof musical
Stars are expected to be out in force tonight as they head to the world premiere of Harry Hill's X Factor spoof musical I Can't Sing!.
The production, which stars Nigel Harman as a Simon Cowell-like show boss, will be a given a red carpet launch at the Palladium in London.
The show takes an affectionate swipe at a number of figures associated with the ITV show with characters based on Cheryl Cole - who is to return to the singing contest later this year - and Louis Walsh. Take That star Gary Barlow gets a nod with a dog named after him.
Simon himself - who last month became a father for the first time, a development reflected in the script - has been involved with the production, as one of its financial backers.
There have been some teething troubles with the show during the early days of its preview run at the theatre, with scheduled performances put back by a few days in order to sort out issues with the way it is staged. And guests at the first preview reported that too was hit by a 50-minute interval, although producers are now understood to have got the delays under control as the show has bedded in.
Among those expected to attend tonight are Simon, Louis and Sharon who returned to the show as a panellist last year. Alesha Dixon and Amanda Holden from Britain's Got Talent are also thought to be heading to the production along with Harry, Myleene Klass and Sir David Jason.
