The two silicone-enhanced blondes are due to appear alongside Libertines frontman Pete Doherty and former TV sports host David Icke, who believes the Royal Family are extraterrestrial lizards, on the show from early next year.
The third series of 'Celebrity Big Brother', where stars are holed up in the 'Big Brother' house for two weeks and gradually voted off by the public, is set to be a ratings winner. Channel 4 bosses are eager to steal the reality show crown from ITV's 'I'm a Celebrity... Get Me Out of Here!', which is considered the most popular reality show.
Silvesdt, also a former Playboy centrefold, and 34DD Douvall are likely to boost the shows ratings -- particularly from male audiences.
Programme maker Endemol, which makes the original 'Big Brother' and 'The Farm' for Five, has warned that the new show will have some surprising twists and turns for the celebrities.
The first 'Celebrity Big Brother' was a ratings success for Channel 4, with chatshow host Vanessa Feltz notoriously losing the plot and comedian and overall winner Jack Dee entertaining the nation with his humorous escape bids.
The second series also fared well, with former Take That boy band member Mark Owen winning the show, and former Page 3 model Melinda Messenger and drum and bass DJ Goldie among the contestants.
