Cheryl Fergison and Alexander Armstrong will appear on 'Your Face Sounds Familiar'.

The former 'EastEnders' actress and 'Pointless' presenter will compete for charity on ITV's new celebrity singing competition, which will see them dress up as famous pop stars.

Other stars set to join the programme include This Morning's Hub host Matt Johnson, Olympian Denise Lewis, 'Emmerdale' actress Natalie Anderson and comedian Bobby Davro.

ITV commissioned the show - which is produced by Endemol, the company behind 'Big Brother' - earlier this year with hopes of launching another hit Saturday night primetime show.

Each week, the celebrities will perform as a musical icon - ranging from Michael Jackson to Beyonce - in a bid to impress a panel of judges including Emma Bunton, Julian Clary and a weekly guest judge. However, in a unique twist, the stars will have no influence over which star they impersonate - relying on a computer randomiser to select their artist, whether they be younger, older, or even of the opposite sex.

The acts will receive points for their efforts with the person at the top of the scoreboard at the end of each episode receiving a cash prize for their charity. At the end of the series, the eventual scoreboard leader will receive an extra bonus for their philanthropic cause.

'Your Face Sounds Familiar' has already been a hit in countries around the world including Spain, Portugal, Ukraine and Italy.

The Saturday night show will be hosted by 'Britain's Got Talent' judge Alesha Dixon and Paddy McGuinness.
