It's the third time that the N-Dubz star has been hauled into the Diary Room to be warned about his language.
His latest incident involved Jasmine Waltz, who asked the rapper if he had ever tried to suck his own penis, with Dappy replying: “Do I look bent?”
In the Diary Room, Big Brother "reminded" Dappy of the rules regarding causing offense and how some viewers might have found his choice of words offensive.
It follows fellow housemate Evander Holyfield being issued with a warning over his comments about homosexuality.
In a chat with Luisa Zissman, the former Heavyweight boxer seemed to suggest that being gay was 'not normal' and could be fixed, comparing it to a disability.
His son Ewin last night defended his day over the comments.
"My dad is the most loving and caring person you will ever meet," he told TMZ. "He treats everyone like a human being... even if they are homosexual.
"My dad feels that being gay is a choice... and naturally that's how things work. You cannot procreate and make a baby with two women, or two men.
"But at the same time, my dad is not going to judge someone for their sexual orientation."
Meanwhile, Bit On The Side host Rylan Clark found himself in hot water with Channel 5 bosses after tweeting about the incident.
He wrote online yesterday: “What Evander just said was disgusting.”
But Rylan removed the message after being told by producers that he needed to remain impartial.
Celebrity Big Brother 2014 airs nightly on Channel 5.
