The 18-year-old actress/singer pulled out of the Jonas Brothers' South American tour in October (10) and checked into a treatment centre to address emotional and physical issues.
After nearly two months of treatment, Lovato was allowed to leave the centre for the first time on Christmas Day for an outing with her family. Her relatives picked her up from the rehab centre and she was photographed out and about, before enjoying a meal at the Hollywood Blvd Cinema Bar & Eatery in Woodridge, Illinois.
She returned to rehab later that evening.
The outing came just days after her legal team settled a dispute with dancer Alex Welch, who threatened to sue over allegations Lovato lashed out at her during an incident on a plane in October (10).
