YouTube Star PewDiePie Uses N-Word During Live Stream: 'I Don't Mean That in a Bad Way'

PewDiePie, aka Felix Kjellberg, was heard saying, 'What a f**king n*****' during live stream.

PewDiePie, the world’s highest-paid YouTube celebrity, has found himself in some trouble for using the N-word during a live video game demonstration.

The Swedish online superstar, whose real name is Felix Kjellberg, was seriously criticized after he blurted out, “What a f***ing n*****.

"Geez, oh my God. What the f***. Sorry, but what the f***.”

The 27-year-old then told his 57 million subscribers, “I don’t mean that in a bad way.” He is then heard laughing.

The outburst came Sunday as he faced an opponent in PlayerUnknown’s Battlegrounds.

Sean Vanaman, co-founder of the game’s developer, Campo Santo, took to Twitter in an angry takedown of PewDiePie’s remark.

“I am sick of this child getting more and more chances to make money off of what we make,” he said. “He’s worse than a closeted racist: he’s a propagator of despicable garbage that does real damage to the culture around this industry."

He also said he would file a copyright claim to force the removal of PewDiePie’s videos.

The YouTube favorite has been in hot water before over off-color jokes and commentary while playing video games. He’s previously made controversial statements about mental illness, race and Nazis.

In February, he was censured for paying an Indian comedy duo to tape themselves holding up a sign saying “Death to All Jews.” Disney’s Maker Studios and Google cut ties with him after that.

He later apologized, but also blamed media reports about the incident with inflaming negative reaction to his post.

On Tuesday, he posted an apology on YouTube. "I'm just an idiot," he said. "It was not OK. I'm really sorry if I offended, hurt or disappointed anyone with all of us," he said.

"I should know better. I know I can't keep messing up like this," he said.

The Swede has made millions for his online commentaries accompanying him playing online games.

The offending video appears to have been taken down.
