In a series of videos posted on Instagram.com on Thursday (01Oct15), the aspiring hip-hop star, real name Chester Hanks, reveals he is clean and sober after undergoing a rehab stint earlier this year (15).

Detailing the low he reached before agreeing to seek help, he says, "A couple of months ago, I was selling coke (cocaine), doing coke until I couldn't even snort it up my nose anymore because it was so clogged. If I can change, you can change. There is a solution.

"I've been trying to get my s**t together and I'm doing pretty d**n good."

And now the aspiring rapper is hoping his journey to good health and sobriety will help others: "At the end of the day all the stupid s**t I was doing, that's not who I am, that's not who I want to be. It's been a long journey for me discovering who I am because of all the pressures that I've dealt with in my life, being the son of my dad and everything and just trying to find where I fit in."

Hanks has made headlines for all the wrong things in recent months - even defending his use of the N-word in his songs.

He's now apologising for offending people.

The Oscar winner's son, who is white, responded to criticism about his liberal use of the racial slur, insisting the term transcends race and is used to express "camaraderie and love" in the hip-hop community.

However, the 25 year old now accepts he was wrong.

"I know a lot of y'all kinda understood the point I was trying to make, but the truth is it's not my place to speak on that," he adds. "I'm genuinely sorry for the people I offended."
