The Vicar of Dibley actress will conduct a U.K. nationwide hunt to find the lead actor for Lord Andrew Lloyd Webber's musical Jesus Christ Superstar as part of her new role.
French, former Spice Girls star Melanie Chisholm, and Australian actor/singer Jason Donovan have compiled a shortlist of hopefuls and the judges will offer their performing arts wisdom when the live shows are broadcast this summer (12).
However, French is concerned she will use rude language on air - so she's indulging in daily foul-mouthed rants to get it all out of her system.
She tells British newspaper the Daily Mirror, "I'm a notoriously rampant swearer and enjoy expletives enormously. I'm trying to use up all my foul language now so that I am severely depleted when it comes to the live telly."
