The housemates were called to the sofas by Big Brother, before informing them that there were rule breaks on Friday (August 31).
Julie's conversation with MC Harvey was relayed to the group, which included her saying that Prince Lorenzo Borghese should be nominated.
The actress looked shocked during the announcement, while other housemates smiled and laughed.
Big Brother then relayed a conversation between Ashley McKenzie, Martin Kemp, Prince Lorenzo and Mike 'The Situation' Sorrentino, where Lorenzo was heard saying of Julie: "I don't care how sweet she is, underneath that sweetness there's a bitter taste."
Julie was told that she would no longer be allowed to wear any of her leopard print clothes or accessories until further notice.
"It's all I've got," she replied, adding: "I do feel terrible, I don't even remember [saying] it."
Prince Lorenzo and The Situation were then called to the Diary Room, where they handed over Julie's clothes.
However, Big Brother told the pair that they must wear into an outfit that had been left under the chair.
The Situation moaned: "I feel like I'm being unjustly punished."
The pair were told that they must wear leopard print boxer shorts until further notice.
Three housemates have been nominated for eviction from the Big Brother house this week.
Celebrity Big Brother continues tonight at 9pm on Channel 5.
