Demi Lovato has officially canceled her remaining Tell Me You Love Me World Tour dates after being hospitalized in July for a reported drug overdose and subsequently seeking treatment at an unnamed rehab facility, E! News has confirmed.

The remaining eight tour dates included stops in Brazil, Argentina, Chile and Mexico.

Live Nation and Lotus Productions said they "wish Demi Lovato the best now and in the future and we hope to see her soon in South America," according to the site.

The companies added that fans can begin receiving refunds for the shows in question on Friday (August 10).

Lovato first opened up about her relapse and overdose on August 5 in a lengthy post uploaded to Instagram.

"I have always been transparent about my journey with addiction," she wrote to her followers. "What I've learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet."

"I now need time to heal and focus on my sobriety and road to recovery," she added. "The love you have all shown me will never be forgotten and I look forward to the day where I can say I came out on the other side. I will keep fighting."
