Following the singer's near fatal overdose, her single 'Sober' has re-entered the Billboard Hot 100.

Having only been released last month, the track only managed to spend a week within the charts. It has since climbed up to position 56, after streams of the song increased by 200%.

'Sober' focuses on the singer's issues with drug abuse, with many fans speculating that she had suffered a relapse.

Lovato was found unconscious by paramedics in her home before being rushed to hospital. She has remained there since July 24. Despite experiencing a number of health issues during her stay, she is expected to fully recover.

Multiple celebrities have come forward to offer their support to Lovato, including Cardi B, Ariana Grande, Dua Lipa and Lady Gaga.

The singer had suffered for years with her sobriety up until her relapse. A close friend of hers told People magazine "Demi never wanted to be a role model. Her sobriety over the last six years was a fight every single day. After she finally got clean, her team was very hard on her and treated her like she was a kid. It’s so hard to have all these eyes on you all the time."
