Demi Lovato leaves rehabDemi Lovato has finished rehab and is heading home to be with her family.

Lovato has "completed her prescribed treatment and an outpatient program near the treatment facility... and getting back to her regular routine," a source close to Lovato tells PEOPLE.

The singer checked into rehab in November to receive treatment for "emotional and physical issues," which some sources have identified as cutting and body image issues. Lovato was also accused of assault by backup dancer Alex Welch, while on the Jonas Brothers World Tour, but the "physical altercation" has already been settled.
