Charlotte Church will be one of the celebrity judges on the new BBC talent show to find a Dorothy to star in The Wizard of Oz musical.
The programme, called Over The Rainbow, is the latest show from musical expert Andrew Lloyd Webber.
The other judges will be John Partridge, who plays Christian Clarke in EastEnders, and Sheila Hancock, who stars in the London musical Sister Act.
Andrew Lloyd Webber will head the panel and Graham Norton is the host.
Over The Rainbow comes hot on the heels of Andrew Lloyd Webber's other successful programmes - How Do You Solve A Problem Like Maria?, Any Dream Will Do and I'd Do Anything.
I'd Do Anything winner Jodie Prenger
Charlotte Church said of her new job: "I'm so looking forward to working with Andrew - he's an icon of the music industry, and a real hero of mine."
Auditions for the part of Dorothy have already started in five UK cities.
The show starts in spring 2010 on BBC1.
