Big Brother housemates Scott Mason and Ashleigh Hughes have been warned over comments they made about their fellow housemate Deana Uppal.
Discussing Deana's eating habits, they lapsed into what the show's producers clearly considered to be racial stereotyping.
Talking about the way she had eaten breakfast cereal with her hands, the Daily Star reports that Scott said: "My dad owned an Indian takeaway and they used to eat everything with their hands. It's the culture."
Ashleigh did an impression of Deana which made the other laugh.
Scott was called into the Diary Room and told: "Earlier today at 4.46pm you had the following conversation with Ashleigh. Big Brother believes that your use of language in this conversation could be seen as stereotyping and therefore potentially offensive. Do you understand?"
He replied: "Oops, I'm sorry."
And Big Brother continued: "Big Brother has no option other than to issue you with a formal warning; if you use this type of language again we may have to consider removing you from the Big Brother house. Do you understand Scott?"
Scott was contrite and answered: "Now that I hear it back it sounds really bad. That's really horrible 'cos I do actually like Deana and I wouldn't want to be horrible, like. I'm sorry for getting carried away and talking about someone, especially like that. I'm really sorry about that."
Ashleigh was called into the Dairy Room afterwards and told: "[Bullying] can include factions developing, tensions, arguments and ostracising of individuals. Examples of bullying could be excluding people ridiculing or humiliating people, name calling, sarcasm and rumour spreading."
She replied: "I am sorry, it's not very nice. I didn't mean to make people feel ostracised, but I understand my actions and I'm really sorry. I am really sorry."
We told you yesterday how Luke Anderson had accused Caroline Wharram of bullying.
