Show chiefs had previously refused to take action against the rapper after he used the term "n****r" in a conversation with Ben Adams at the weekend.
However, Channel 4 has now confirmed that the 45-year-old was reprimanded in a Diary Room conversation on Sunday night.
A spokesperson told The Mirror: "Big Brother called Coolio to the Diary Room to remind him about the rules regarding unacceptable language. Big Brother will continue to monitor the situation."
Meanwhile, a show insider told the Daily Record: "Coolio is testing the bosses' patience with some of his stories and bad language. The warning wasn't televised because that could inflame the situation more."
