It's definitely been a rough week for YouTube vloggers Jake and Logan Paul.

After video footage surfaced of Logan filming a dead body in a Japanese forest, his younger brother Jake is now coming under fire for behaviour of his own.

On Friday, TMZ posted a leaked video allegedly showing Jake rapping using the word n*****.

The video is purported to show the actor and YouTube personality hanging out with friends during 2017's Coachella music festival and fresstyling to Rae Sremmurd's "Throw Sum Mo."

Jake is heard rapping lines like "little ass n---as" and "I whip it like my n---a Richie Vetter" in the video taken at a rented house in Palm Springs.

The Independent has contacted representatives of Jake for comment, but has yet to hear back.

The apparent use of the racial slur has raised eyebrows for the vlogger who caused an uproar on January 3 with a video titled "I lost my virginity."

The original thumbnail of the video showed Jake lying under his nearly nude girlfriend Erika Costell, but the actual video didn't contain any NSFW material; it was just age-gated for users under 18.

Since uploading "I lost my virginity," Jake has replaced the thumbnail with something less controversial.

Jake currently has 13m subscribers on YouTube and 3m followers on Twitter.

He first rose to fame on the app Vine and for his role on Disney's Bizaardvark.
