Demi Lovato remains in the hospital following her apparent overdose last week.
It's been six days since the 25-year-old "Skyscraper" singer was taken by ambulance to Cedars Sinai Medical Center in Los Angeles, and now E! News has learned that Lovato is sick and suffering from extreme nausea and high fever. While it's not known when Lovato will be released, E! News has learned that she is under the care of medical experts and expected to make a full recovery. Lovato's family and manager just want Demi to get healthy and they are focused on getting her healthy and taking it day by day.
E! News has also learned that Lovato's family and ex-boyfriend Wilmer Valderrama are still with her to support her.
Following her hospitalization last week, a source told E! News that Lovato has been in a "downward spiral" in recent months.
"She had a sober coach who she cut out of her life a few months ago. She's been in a downward spiral ever since and has not been doing well," the insider shared. "She's been heavily using and her friends have been very worried that this was going to happen."
While another a second source told E! News, "Demi has been suffering her addiction disease for months now and has been spiraling."
Lovato, who has been very open about her struggles with drugs and alcohol, released a song last month called "Sober," about breaking sobriety.
"She made the decision to come out publicly about her relapse recently because she thought she could inspire her fans and it would help her keep on track, but she has been battling her own demons for months," the insider continued. "Demi has been trying to stay busy with her tour but she has definitely been having her ups and downs."
Another insider also shared with E! News that Lovato is "grateful to be alive" following the overdose.
