Pete, who shares two children with the glamour model, has raised concerns about the effect his ex-wife's appearance may have on their children.
Katie has made no secret of her colourful past and speaks candidly about her sex life which Pete feels leaves their children open to ridicule.
A source close to the star said: "Pete's got a zero tolerance policy about CBB in the house, he's banned any talk of it or even a second of it to be shown on his TV when the kids are over."
Pete, who married Katie after meeting on I'm a Celebrity...Get Me Out Of Here in 2004, feels that his ex-wife's behaviour on the show is unsuitable for his children, with an insider revealing: "He thinks Katie is far too sexualised on it and says he doesn't want his children watching the horror show."
This series of the long-running reality TV show is brimming with controversy this year and contestants have gone as far as to question each other's parenting skills.
