There are still a lot of questions surrounding Demi Lovato’s overdose recovery—specifically when, or if, the singer will enter rehab.

According to several outlets, Lovato remains hospitalized at Cedars-Sinai Medical Center, where she was admitted one week ago for an apparent drug overdose. Sources told People magazine the 25-year-old experienced health complications over the weekend, but is expected to make a full recovery.

“It’s too soon to say what the next steps are in terms of entering treatment,” an insider told People about Lovato’s potential rehab stint. “Right now everyone is focused on getting Demi physically healthy.”

Another source provided details about the singer’s recent health problems. “Demi wasn’t doing well over the weekend. She came down with a fever and showed signs of an infection. She is currently being treated for issues that are very common after a drug overdose. She will need to stay in the hospital for a few more days, but is expected to make a full recovery.”

News of Lovato’s hospitalization broke last Tuesday, shortly after the singer was reportedly found unconscious at her Hollywood home. Though the details of the overdose have not been revealed, insiders have refuted the rumors that heroine was involved.

Lovato’s struggles with substance abuse have been well documented over the years, and previously entered rehab in 2010.

Sources said Lovato’s loved-ones believed another rehab stint is necessary; however, they’ve yet to discuss future treatment with the singer because, 1) They’re focusing on improving her health condition, and 2) They’re unsure if Lovato will be open to readmission, as she reportedly refused treatment prior to her recent overdose. 

“We just don't know where her head is at,” a source told TMZ.
