Katie, 36, entered CBB as a late arrival and has remained fairly passive with her fellow contestants, despite ongoing tensions in the house.
However, last night Katie was grilled by outspoken Katie Hopkins after she revealed the government pay for her son Harvey's transport to and from school.
Harvey, 12, suffers an array of disabilities and learning difficulties and Katie P insisted she is entitled to the help as she pays tax. Although the women didn't come to blows, The Pricey did later admit that Katie H had "come close" to pushing her buttons.
Watching from home, the star's brother Danny now believes it is only a matter of time before the former glamour model blows her lid.

Danny, who is currently manning Katie's Twitter account while she is in the CBB house, told her followers: "Have a feeling the champagne bottle that is #cbbkatieprice may explode very soon - think I'll leave it on that thought #cbb."
When Katie first entered the CBB house, many fans predicted fireworks. In the past year, Katie Hopkins has insulted both the star's looks and her choice of name for baby daughter Bunny, and she also has history with Alicia Douvall.
Before Alicia was evicted on Friday night, Katie had spoken to her about their past boyfriends - Dane Bowers and Dwight Yorke - however the girls were happy to put any differences to one side.
And despite their disagreement last night, KP and KH have actually formed a friendship on the show.
But is all that about to change? Only time will tell!
