Miquita Oliver was reportedly suspended from T4 after insulting Ke$ha backstage at the NME Awards.
According to The Mirror, Oliver used a four-letter word to describe the 'TiK Tok' star and was overheard by her management team.
A source said: "Miquita was having a really bad day. She blurted out the angry words and thought no-one had heard her. She didn't mean anything personally, it was a spur of the moment thing.
"But Ke$ha's team caught it and were outraged. They complained to Miquita's bosses who dealt with her straight away. She was given a serious telling off, and told to take some time off."
A Channel 4 spokesperson: "Miquita Oliver was involved in an issue at the NME Awards that she now regrets.
"The matter has been dealt with swiftly by T4, and Miquita has also sent an apology to those concerned and it has been noted.
"She will remain a key part of our T4 presenting team and viewers will see her on air as normal over the coming weeks."
