Demi Lovato VideoDemi Lovato is back! After leaving a treatment facility in January, Lovato reached out to fans to talk about the "darkest time" of her life in a new online video.

The singer checked into rehab in November to receive treatment for "emotional and physical issues," after being accused of assault by backup dancer Alex Welch, while on the Jonas Brothers World Tour.

"Your support is what got me through this," the Disney star said (via Cambio). "The journey has been very, very difficult the past few months. I was dealing with issues that I know not only girls just my age but of all ages are dealing with."
