Lovato shared the photos on the internet just as she admitted to doing drugs while promoting her sobriety several years ago. In her new documentary, Simply Complicated, Lovato admitted that she was still using substances for a period of time in 2012, Daily Mail reports.

"I wasn't working my program, I wasn't ready to get sober," she said. "I was sneaking [cocaine] on planes, I was sneaking it in bathrooms, sneaking it throughout the night...I went on a bender of like, two months where I was using daily."

"There was one night when I used a bunch of coke and I popped a few Xanax bars, and I began to choke a little bit," she continued. "My heart started racing, and I thought to myself, 'Oh my God, I might be overdosing right now.'"

In 2010, Lovato went back to rehab to seek treatment for a dependence on alcohol and drugs. She also was seeking therapy for an eating disorder and self-harming.

The turning point in Lovato's sobriety journey with substance abuse was when she realized the potential damage that could be causing her loved ones.

"The most important thing to Demi is losing people, losing people that she cares about and that love her," her sober coach, Mike Bayer said.

On Wednesday of this week, Lovato shared before and after photos of her recovery. See the snap here.
