The Miss India UK had a bitching session in the garden with Luke Anderson, Adam Kelly and Sara McLean about the 20-year-old Surrey boarding school girl.
"Considering that girl has had one of the best educations and her parents are supposed to be so well off, it hasn't done her any favours at all," moaned Deana.
"She's so flipping rude. She's got no manners at all, no sensitivity, she's just unbelievable."
Deana continued: "She has no sense of reality or what life is because her parents have threw money at her.
"She doesn't know how to treat people, she doesn't know how to show any respect, all she can do all day is be sarcastic and make people feel like s**t."
Both Deana and Caroline are among the eight housemates nominated for eviction this week.
Big Brother continues daily on Channel 5.
