One of the top stars on YouTube has been doing damage control since eliciting backlash over his use of the “n-word.” The AP reports that Swedish-born comedian and video producer PewDiePie — whose real name is Felix Arvid Ulf Kjellberg — apologized on a live video stream.

“It was something that I said in the heat of the moment — I said the worst word I could possibly think of,” Kjellberg says in the new video, adding: ‘It just sort of slipped out.”

Kjellberg, 27, has been the focus of a series of controversies for his videos, which consistently push the envelope. You can watch his latest apology below.

Kjellberg adds in the video: “I’m disappointed in myself, because it seems like I’ve learned nothing from these past controversies.” He also calls himself an “idiot.”

“The online star, who rose to fame by posting videos of himself playing and commenting about video games, earlier had to defend himself over anti-Semitic allegations,” the AP notes.

Kjellberg reportedly has more than 57 million YouTube subscribers.
