Demi Lovato is still in hospital after her alleged drug overdose due to "complications".
Sources told TMZ that the 25-year-old is still at Cedars-Sinai hospital in Los Angeles six days after she was admitted because she is suffering some "complications" related to the overdose, reportedly including extreme nausea and a high fever.
Lovato was rushed to hospital last Tuesday (local time) after an unknown drug overdose. Representatives for the pop singer have not provided any details on what led to the singer's hospitalisation.
Lovato indicated in a new song released last month that she had relapsed after six years of sobriety.
She sings "Mumma, I'm so sorry I'm not sober anymore/And daddy please forgive me for the drinks spilled on the floor."
In her YouTube documentary released last year called Demi Lovato, Simply Complicated, she openly discusses her cocaine use and battles with alcohol.
