'Kiss Kiss' Singer Holly FumingHolly ValanceGorgeous singer Holly Valance has turned down a reported £100,000 to appear on next month's Celebrity Big Brother.       

Show bosses are gutted  the Aussie babe, singer of Kiss Kiss, snubbed the offer, as they are desperate for some top young totty to wow viewers.

Three celebs are still needed to complete the line-up, with little more than a week to go.       

An insider told the Sun: "They were desperate to get a young, beautiful star like Holly to keep viewers tuned in but she was too busy with acting commitments in America."       

Sven-Goran Eriksson's partner, Nancy Dell'Olio, and and Cherie Blair's style guru, Carole Caplin, have also turned down offers to appear.       

So far those confirmed reads like a Who's Who of z-list celebs.       

Lined up are ex-telly presenter David Icke, racing pundit John McCririck, Leslie Ash's husband, Lee Chapman, and Danish film star Brigitte Nielsen.       

The show starts on January 6.
