Sia Celebrates 8 Years Of Sobriety

Last week, Sia revealed that she had celebrated eight years sober. She commemorated the accomplishment with a simple, but powerful tweet to all of her followers on Monday night - especially to those following in her footsteps.

"Eight years sober today. I love you, keep going. You can do it," the singer-songwriter shared on Twitter and Instagram. Fans of the songstress replied with messages of love and support.

"I Was Always A Drinker But Didn't Know I Was An Alcoholic."

The private pop star has been open about her battle with substance abuse, which was exacerbated by her rise to fame in 2005.

In an interview with Billboard in 2013, she previously opened up about her history with addiction and how she got addicted to Vicodin and Oxycodone.

"All I wanted to do was write for pop stars," she shared. "For one reason or another it never happened for me. Then I got seriously addicted to Vicodin and Oxycodone, and I was always a drinker but I didn't know I was an alcoholic. I was really unhappy being an artist and I was getting sicker and sicker."

In another interview with Nightline in 2014, Sia confessed that her life began spiraling out of control in 2005.

"I was extremely depressed at the time, that was one of my lowest points," the 40-year-old said. "I don’t think I ever would have stopped drinking had I not got hooked on Xanax and OxyContin. I don’t think I was taking them for more than maybe 10 months before I hit rock bottom." By 2010, she began a 10-step program.

Opening Up About Under The Wig

Sia's chart topping song, "Chandelier," is also a dark reference to alcoholism.  "I wrote that song because there's so many party-girl anthems in pop. And I thought it'd be interesting to do a different take on that," she said during an interview with NPR in 2015. "For some reason... I didn't wanna give it away."

Most recently, the "Cheap Thrills" singer chatted with James Corden about how her infamous wigged look is about her sobriety just as much as it is about the fun of a good mystery.

"I was an alcoholic and a drug addict, and I sobered up and decided I didn't want to be an artist anymore because I was starting to get a little bit famous," she reflected. "It was destabilizing in some way. So I thought what doesn't exist in pop music at the moment? And it was mystery." Check out the video below.

Sia isn't the only celebrity to be open about their struggles with sobriety. Stars like Dax Shepard recently celebrated 14 years of being sober, Eminem just passed 10 years, and Ben Affleck is currently seeking treatment for his alcoholism.
