There's even more trouble for pop star Justin Bieber. The 20-year-old singer is in the middle of a racism scandal after two videos leaked of him using the N-word and making offensive jokes about African Americans.

In the first clip, a younger Bieber joked about black people and chainsaws and in the second video he was seen singing about "killing a n**er" and joining the Klu Klux Klan, The Sun reports.

Now according to the New York Post's Page Six, a third video is expected to be leaked in the next couple days. A source told the newspaper that the alleged new clip shows the pop star telling even more offensive jokes about African Americans.

According to Page Six, the "Boyfriend" singer once again drops the N-word, asks a friend if "his parents are as black as [rapper] Akon" and jokes about "black people liking watermelons." The source said the alleged video is "15 to 20 minutes long."

It's been said that the clips are from 2009. The source told Page Six that the alleged third video "explicitly shows this was more than just one regrettable joke."

Another source told the newspaper that the clips being leaked are all from the same footage and someone might be trying to blackmail the pop star.

"This is all the same footage someone had been trying to blackmail Justin over for years," the source said. "It was made when he was 14 or 15. At the time, he realized it was wrong ad went to Usher and Will Smith, who helped educate him. He's now a 20-year-old who's taken responsibility."

Bieber recently issued a second apology after TMZ posted a video of the pop star singing about killing African Americans. In the clip, he changed the words to his hit 2009 song "One Less Lonely Girl" to "One Less Lonely N**er." He also joked about joining the Klu Klux Klan, The Sun reports.

"Facing my mistakes from years ago has been one of the hardest things I've ever dealt with," Bieber said in a statement to US Weekly. "But I feel now that I need to take responsibility for those mistakes and not let them linger. I just hope that the next 14-year-old kid who doesn't understand the power of these words does not make the same mistakes I made years ago. At the end of the day I just need to step up and own what I did."

Bieber also tweeted a link to his Instagram account which contained a photo of Bible verses.
