R&B superstar Usher, who has been a mentor for Justin Bieber throughout his career, has finally addressed the 20 year-old's recent racism scandal.

The 35 year-old singer is featured on the front cover of the latest issue of Nylon Guys and speaks candidly of watching Bieber deal with all aspects of fame, and what kind of pop star he is today.

However, it is still unclear if User opened up about this before or after the two pieces of footage surfaced.

"I gave every bit of advice and always told him it was up to him if he really wanted this. Now that he has it, as an adult, it's his to manage. Do I turn my head in shame based off of what I see, what I know? Nah, I don't because it's all part of life's process," he explained.

Adding, "Am I in it with him? Yeah. It's unfortunate. I hate some of the things I hear. Is it all true? I don't know."

Earlier this week Bieber caused outrage after a video was published by the British tabloid The Sun of Bieber asking, "Why are black people afraid of chainsaws?"

The singer, who was smirking, then delivered the offensive punch line, saying: "Run n-----, n-----, n-----, n-----, n-----."

Only days after this video emerged online, another clip showing Bieber using racial slurs surfaced. He is seen rapping about killing a 'N-word' and joining the Klu Klux Klan, as well as changing the words of his 2009 hit 'One Less Lonely Girl' to One Less Lonely N----.'

But Usher seemed to defend the 'Baby' singer's behaviour. "I will tell you this: Success comes with a price. Every person that has grown up, grows through something. It ain't just perfect from the beginning," he stated.

Bieber issued an apology for his "ignorance" as he was just "a kid then," after the first tape was released, and on Thursday (June 5th) he once again said he is "sorry for all those I have let down and offended," following the second tape surfacing.
