“Demi is committed to their well-being, and throughout their life, they plan to do regular check-ins to make sure they are putting themselves first,” the insider said.

A rep for the Grammy Award nominee has yet to provide a comment, following People‘s request.

Lovato first went to rehab in late 2010 before they stayed in a sober-living facility in 2012. The “Confident” singer joined another in-patient program following their 2018 overdose.

Last year, the Disney channel alum revealed in their YouTube docuseries “Demi Lovato: Dancing with the Devil” that even after their overdose they still drank and smoked marijuana in moderation, which they confessed “isn’t for everyone.” However, last month, they publicized that since then, they’ve completely ditched the “California sober” lifestyle.

Although Lovato suffers “brain damage” as a result of experiencing three strokes and a heart attack from their overdose, they told People last year that they “wouldn’t change a thing” and they’re “so proud of the person I am today.”
