Demi was scheduled to perform in Mexico and South America over September and November but has pulled the tour dates to focus on her health.
“Unfortunately, Demi Lovato has cancelled her upcoming Tell Me You Love Me Tour dates in South America, as she is focusing on her recovery,” Live Nation and Lotus Productions said in a statement.
“The six-city tour was scheduled to visit Chile, Argentina, and Brazil starting Nov. 14. Ticket refunds will be available at the point of purchase and credit card purchases will be automatically refunded.”
Demi was taken to hospital on July 24 following an overdose.
She broke her silence on social media shortly after, thanking her fans for their support while she recovered.
"I have always been transparent about my journey with addiction. 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," she said.
"I want to thank God for keeping me alive and well,” she wrote, before thanking all of her fans for standing by her side. “Your positive thoughts and prayers have helped me navigate through this difficult time."
