'Over The Rainbow' judge John Partridge has revealed that his perfect Dorothy on the reality show should pose a "triple threat".

According to Digital Spy, the former 'EastEnders' star said: "I think at this stage when we are down to the final 20, all these girls have a sensibility that is right for Dorothy."

"But we're looking for a girl who can sing contemporary, but also they have to able to hold an old-fashioned standard."

"I'm also wanting what we call an old-fashioned triple threat. I'm looking for someone who can dance, sing and act."

"Sheila [Hancock] is probably more on the acting, Charlotte [Church] the singing, I'm looking for the whole package."
