The 24-year-old son of Tom Hanks and Rita Wilson recently revealed that he is 50 days sober after completing rehab.

Chet Hanks made the announcement on Instagram on November 19, and thanked his supporters and God for helping him abstain from alcohol and cocaine.

"I've been struggling with substance abuse since I was 16 years old," Hanks revealed. "Finally at the age of 24 I decided to get some help.

"With 50 days of sobriety under my belt, I can honestly say I'm the happiest I've ever been. I'm thankful for my family and everybody that cares about me, including my fans. 

"I've been blessed with the programs of AA and NA which allow me to rise above this disease. I'm learning to accept my faults and be ok with being human.

"If anybody that sees this struggles with addiction, feel free to reach out. Thank you all for the love and support! GOD IS REAL!!!"

The aspiring rapper allegedly spiralled into addiction over the past year, after being a long-time marijuana  user. Chet's famous parents are reportedly saddened by their son's addiction but doing everything they can to help him.

"Chet developed a problem with cocaine this year," a source told the magazine.

"He was always a big pot smoker, but I never thought he'd go in this direction, and to the degree that he had to spend time in rehab in California this fall."

"Of course, this was devastating to his dad and mom," a source told Star Magazine, "but they've done everything they can to help him, and fully supported him in his decision to get sober."

Chet,  who uses the stage name Chet Haze, referenced alcohol and marijuana frequently in his rap songs, but insisted that he separated his image from his real life. 

"It's part of college life; I wanted to rap about something that I do," he said in a 2011 interview. "But I wouldn't say that's what my life is all about. …I'm not some caricature of a person who just drinks and smokes weed and parties all the time."
