Demi Lovato is sober for 90 days

Demi Lovato’s mom Dianna De La Garza has a happy update for her daughter’s fans: Demi is doing well and has 90 days sober, reports USWeekly.com.

“Yes, she has 90 days,” she revealed during her appearance on Conversations With Maria Menounos Opens a New Window, adding, “And I couldn’t be more thankful or more proud of her because addiction being a disease, it’s work.”

The Sorry Not Sorry songstress’ mother admitted that she didn’t know the extent of her daughter’s problem before the overdose. “I knew that she wasn’t sober, but let me clarify I didn’t know what she was doing. I just knew that she wasn’t sober.” When asked what she thought caused Lovato’s relapse, De La Garza replied, “I can’t really say for sure. I don’t really know.”
