“Yes, she has 90 days [of sobriety]," De La Garza revealed. “And I couldn’t be more thankful or more proud of her because addiction being a disease, it’s work. It’s not easy. There are no short cuts.”
When asked if she knew the full extent of Lovato's struggles with substance abuse before her hospitalization, the singer's mom replied: “I knew that she wasn’t sober, but let me clarify. I didn’t know what she was doing….because she doesn’t live with me. She’s 26. I just knew that she wasn’t sober. And that’s all I really knew at that time.”
Demi Lovato Breaks Her Silence After Apparent Overdose Last Month: 'I Will Keep Fighting'
Following her release from Cedars-Sinai Medical Center in early August, Lovato entered a rehab facility for further treatment. Her 16-year-old sister, actress Madison De La Garza, shared an update on the Camp Rock star earlier this month.
"Demi's doing really well," Madison said on the podcast, Millennial Hollywood with Dakota T. Jones. "She's working really hard on her sobriety and we're all so incredibly proud of her. It's been crazy for our family. It's been a lot, but we've been through a lot together."
"Every time we go through something, we always come out the other side 100 times stronger than before," she noted of her family's strength. "So, we've just been so thankful for everything, for the little things."
A source previously told ET that Lovato's family and friends have been a huge source of support for her.
"Demi understands that every day is a struggle to stay sober, and she's doing everything she can to get back to where she was," the source said. "Demi is thankful to be surrounded by so many people who love her, and want to see her win."
