Demi Lovato has reportedly left the in-patient rehab facility she entered last week in search of additional treatment in Chicago.

According to People, Lovato, 25, and her mother, Dianna De La Garza, left Los Angeles late Thursday night and flew to Chicago to meet with a psychiatrist who specializes in mental health and sobriety treatment. Citing an unnamed source, People reported that someone close to the singer said "she's in the midst of recovery," adding "it's going to be a long road, and Demi knows that. Emotionally, it hasn't been easy but she's doing okay."

A spokesperson for Lovato could not be reached for comment at press time. TMZ reported that the trip to Chicago was organized by the singer's Los Angeles care team and she is expected to be in the city for several days of treatment before returning to the LA rehab facility she checked into on Saturday. Lovato was rushed to Cedars-Sinai Hospital in LA on July 24 after suffering a reported overdose.

Lovato has previously spoken about her struggles with an eating disorder, self-mutilation, drugs and alcohol. She celebrated six years of sobriety in March but recently relapsed, revealing the news in the song "Sober," released in June. The track hit a new peak this week on the Billboard Hot 100 chart, reaching No. 47. She has canceled the rest of the dates on her planned fall tour in order to focus on her recovery.

The singer posted an emotional note to Instagram on Sunday, the first word from her since the incident at her Hollywood Hills home in July. "I have always been transparent about my journey with addiction," she began. "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 want to thank God for keeping me alive and well. To my fans, I am forever grateful for all of your love and support throughout this past week and beyond. Your positive thoughts and prayers have helped me navigate through this difficult time."
