'We didn't know if she was going to make it' - Demi Lovato's mum recalls overdose

Demi Lovato's mum has broken her silence on her daughter's high profile drug overdose with an emotional on-camera interview.

Speaking to Newsmax TV, Dianna De La Garza recalled the moment she found out her daughter had been rushed to hospital after she was discovered unconscious at home.

De La Garza explained she had already received cryptic texts from friends who had seen headlines about the incident when Lovato's assistant called and told her the bad news.

"I hesitated to ask, but I had to ask her - I remember it just seemed like the words took forever to come out of my mouth. I said, 'Is she OK?'" De La Garza said.

Lovato's assistant replied that the pop star was "conscious but not talking".

"That when I knew that we were in trouble," De La Garza said.

De La Garza explained that she rushed to her daughter's bed side, but was shocked by what she saw when she got there.

"She didn't look good, at all. She was in bad shape," she recalled.

It wasn't until De La Garza told Lovato "Demi, I'm here, I love you," that she got a response: "I love you too".

Paramedics reportedly revived Lovato with Narcan, a treatment for opiod overdoses. She remained at Cedars-Sinai Hospital for two weeks.

"We just didn't know for two days if she was going to make it or not," De La Garza said.

Now released from hospital and in rehabilitation, the 26-year-old's mother says she's "doing really well."

"She's happy, she's healthy," she said.

"She's working on her sobriety and she's getting the help she needs."

De La Garza credited the outpouring of support Lovato received as playing a major role in her recovery.

"I feel like the reason she's alive today is because of the millions of prayers that went up that day," she said.
