Demi Lovato’s mum has given fans an update about the singer’s condition three months after she was hospitalised for a suspected drug overdose.

Dianna De La Garza appeared on an episode of the Conversations with Maria Menounos podcast on Sirius XM where she revealed that her daughter is recovering well and has just hit the 90 days sober mark.

“She has 90 days and I couldn't be more thankful or more proud of her, because addiction, being a disease, it is work,” she told the host. “It's very hard, it's not easy, and there are no shortcuts.”

As for what she thinks prompted the 26-year-old to relapse, Dianna pointed out: “It can be any number of reasons. We lost five close members of our family in one year while I was writing the book, my grandfather, my grandmother, two uncles. We lost five people just in a span of a few months.

“My grandmother and my grandfather were older and they were in a nursing home, but my uncles, that was kind of a shock. And then I lost a grandmother on my father's side and so even through all of that, losing all of those people, she didn't relapse. So, it's hard to say. You couldn't say because we lost five people in our family that caused a relapse.”

She added: “I also think that when you're young and sometimes you think, maybe I can go do this and it won't affect me, but with an addiction you just can't do that. It's a slippery slope.”

Demi herself took to Instagram in August to thank fans for their well wishes and to reiterate that she will “keep fighting” her illness going forwards.
