Eminem is one of the world's most renowned rappers.

Eminem, real name Marshal Mathers, first came onto the hip-hop scene in his home town of Detroit, Michigan, in 1997.

After quitting school, Eminem was determined to make it big as a rapper.

And throughout the early 90s, he worked tirelessly on making a name for himself in the underground world of hip hop - Something which proved to be quite the challenge for a white man.

His success certainly wasn't immediate.

And it took him quite some time to establish himself in the industry, with Detroit's veteran MCs and DJs laughing the "skinny white boy" off from the stage.

For years, Eminem worked menial jobs just to make ends meet.

And his debut album, the 1996 Infinite, sold poorly.

But everything changed in 1997.

Eminem's freestyle skills and unique persona, Slim Shady, caught the attention of rapper and record producer, Dr. Dre, at an LA rap battle.

Dr. Dre saw something in the up-and-coming rapper...

And with the producer as his mentor, Eminem released the iconic The Slim Shady LP in 1999, which went on to sell millions of copies and win him 2 Grammy Awards and 4 MTV Video Music Awards.

It was onwards and upwards from there.

In 2000, he went on to release The Marshall Mathers LP, which included some of his most popular tracks such as "Stan" and "The Real Slim Shady."

His fourth album, The Eminem Show in 2002 was just as successful...

And in that same year, the musician made his acting debut in the movie, 8 Mile, which was based loosely around his own life and growth and success in the world of hip hop.

However, despite all of his success...

Eminem certainly hasn't been shy of controversy.

The rapper has frequently come under fire for being offensive...

And many have slammed the rapper as being "sexist" and "homophobic" in his music.

He had often rapped about killing his wife, Kim...

And was arrested and charged with assault in 2000 when he allegedly pistol-whipped a man he saw kissing her.

Eminem has built his image around an angsty, rebellious young man who simply "doesn't give a f***".

And he has publicly blasted many famous faces in his songs, including Limp Bizkit's Fred Durst, Christina Aguilera, and Will Smith.

Many credit this turbulent and disruptive attitude to his difficult upbringing.

Rumors of Eminem's abusive childhood have circulated for years, and the rapper famously had a difficult relationship with his mom, Debbie Nelson-Mathers.

And, on top of all this, the rapper was fighting a long and hard battle with addiction.

Throughout the early years of his career, Eminem struggled with addiction to prescription medications such as Vicodin, Valium, and Xanex.

This addiction quickly took over his life.

In the 2013 documentary, How To Make Money Selling Drugs, Eminem briefly opened up about his addiction and admitted that, at his lowest point, he was taking up to sixty Valium and thirty Vicodin pills every day.

But for years, he didn't think he had a problem.

Because he wasn’t “out there shooting heroin", he didn't acknowledge his addiction as a "real" addiction. “I don’t know at what point exactly it started to be a problem. I just remember liking it more and more."

But, in 2007, he overdosed.

The rapper's organs began quickly shutting down, and he was rushed to the hospital, where the doctors had a grim message. “The doctors told me I’d done the equivalent of four bags of heroin," he said at the time. “They said I was about 2 hours from dying. They were gonna have to put me on dialysis. They didn't think I was gonna make it. My bottom was gonna be death."

This was when he knew things needed to change.

He vowed never to touch drugs again, but his road to recovery was difficult, with him relapsing several times.

But his children helped to keep him focused on his recovery.

The rapper realized that he wanted to be around for when his daughters grew up, and continuing with his drug habit wasn't going to allow that to happen.

So, shortly after his overdose, he enrolled himself onto a gruelling detox program.

Elton John became his mentor and would check in on him once or twice a week to ensure he was on the straight and narrow.

And, fast forward to today...

Eminem is now celebrating twelve years sober.

Eminem shared his incredible accomplishment to Instagram...

Where he shared a photo of his twelve years pin alongside the caption: "Clean dozen, in the books! I’m not afraid."

People have been taking to social media to congratulate the rapper...

With many commending him for overcoming his on-and-off addiction.

He is an inspiration to everyone battling with addiction.

If Eminem can do it, so can you!

Congratulations, Eminem!
