Demi Lovato's long-time backup dancer and friend Dani Vitale is denying rumours that she provided drugs to the singer.

In an emotional essay shared on Vitale's Instagram, the dancer made it clear that she was not responsible for "Echame la Culpa" singer's relapse, reports variety.com. "I have never touched nor even seen a drug in my entire life. I do not do drugs nor would I ever encourage or supply them to anyone I love," Vitale wrote.
