Demi Lovato's condition hasn't improved since she hospitalised after a drug overdose last Tuesday.

Whilst the singer had been on the road to a fully recovery, she suffered from a high fever and nausea over the weekend. However, her condition is expected to stabilise.

The 'Confident' hit-maker was unconscious when paramedics discovered her in her home last week. Early reports claimed that Lovato had taken heroin, though these were later dismissed.

One of Lovato's back-up dancers has since come out and called for an end to speculation as to what drugs the singer may have taken. Dani Vitale wrote, "There is no need for any negativity towards the ones who care about Demi at this time. There is too much of it in the world as it is".

Lovato has always been open about her addictions, penning the track 'Sober' which was written to mark her sobriety.
