Demi Lovato's back and better than ever!

The Disney starlet was spotted smiling while out in Santa Monica Friday afternoon after finishing her stint at a treatment center.

In late November, the 18-year-old Camp Rock 2 star dropped out of her tour with the Jonas Brothers (months after splitting with Joe Jonas) and checked into a facility "for emotional and physical issues."

And despite a one-and-a-half day leave to spend Christmas Eve and Christmas with her family (she returned to the center both evenings) Lovato remained completely committed to getting better.

"It's entirely up to the treatment to see how long she will be in there," an insider told last year. "She will stay as long as the doctor's tell her she needs to stay."
