Demi Lovato's mom is giving fans an update on the singer's health, announcing she's 90 days sober, but says she knew her daughter was not sober even before her overdose.
Dianna De La Garza was on Maria Menounos' Sirius XM show on Friday and said she "couldn't be more thankful or more proud" of her daughter.
Opening up about Demi's addiction, Lovato's mom admits she knew at the time her daughter wasn't sober, but "didn't know what she was doing."
The singer has been in rehab since August, and just last month, Dianna spoke out for the first time since Demi's overdose, crediting faith and fans for helping the 26-year-old make it through her recovery process.
It's been three months since Demi was rushed to the hospital after overdosing in her home.
