Sue, who has taken control of her daughter's career since her split from Can Associates, is currently considering the offer to take part in the show. Bosses are lining up Kerry's ex Mark Croft in case Sue declines the offer.
"Kerry is very outspoken and so is Sue so there is bound to be a lot of friction between them in the house," a source told The People. "Theirs is not a typical mother and daughter relationship - it is very volatile and will make great TV.
"Sue is currently thinking it over but it's fair to say she's tempted, especially as she needs the money - just like Kerry. When Kerry first heard they had asked her mum she thought it would be a nightmare but now she thinks it could work out well for both of them."
Producers are hoping that Kerry will open up about her failed marriages and battle with drugs and depression during her time in the house. She has apparently told them: "Just clear my debts and I'm in," leading to a £285,000 offer being made.
The source added; "Kerry is worried because she can't cook or clean and so won't be able to pull her weight, which won't go down well with her housemates. She is also nervous because the public will see what a scruff she really is."
Celebrity Big Brother starts next month on Channel 5. Snoop Dogg, BBC Radio 1 DJ Tim Westwood and Tiger Woods's alleged mistress Rachel Uchitel are also rumoured to be taking part.
