Singer Demi Lovato is still sober, 16 months after she was rushed to hospital due to suspected drug overdose. The 27-year-old singer has spoken up after she was reported to have broken her sobriety by smoking weed and drinking margaritas, reports aceshowbiz.com. The former child actress, who appeared on TV series "Barney & Friends" took to Instagram Stories on Wednesday to dispel the rumours, writing on a plain black background, "Don't believe the rumours".

She additionally posted a black screen on her feed and wrote in the caption: "The next time you hear from me, I'll be singing....." It's not clear whom her posts were directed at, but some fans have come to her defence following rumours of her supposed relapse. "Leave my Demi alone stop spreading hate and rumours," one wrote in the comment section.
