Demi Lovato is “working hard on bettering herself” whilst in rehab

An insider said: “She’s working very hard on bettering herself and staying on the right path. Sobriety is the most important thing in Demi’s life right now.”

Whilst in rehab, the ‘Sober’ hitmaker has been visited by her family, as well as her former boyfriend Wilmer Valderrama.

The insider added to ‘Entertainment Tonight’: "Demi has been fortunate to have her family and friends for support during this time. Demi’s mother and her ex, Wilmer, have visited her in rehab when they can.”

Wilmer, 38, and Demi split in 2016 following six years of dating but have remained close, and the former ‘That 70s Show’ star was recently reported to have put his life on hold in the wake of his former partner’s health scare.

Meanwhile, Demi’s mother Dianna de la Garza, admitted she was still “shaken” by the incident, but said her daughter is now "happy" and "healthy" as she works toward her sobriety.

She said: "It's still a really difficult thing to talk about. I literally start to shake a little bit when I start to remember what happened that day. [Demi's assistant called and] said, Demi overdosed. So, I was in shock. I didn't know what to say. It was just something that I never, ever expected to hear, as a parent, about any of my kids.

"I just feel like the reason she's alive today is because of the millions of prayers that went up that day when everybody found out what was happening. I don't think she would be here if it hadn't been for those prayers and the good doctors and Cedars-Sinai. They were the best. I couldn't have asked for a better team of people to save her life.

"She's happy. She's healthy. She's working on her sobriety, and she's getting the help she needs. That in itself encourages me about her future and about the future of our family."
