Demi Lovato was spotted out of rehab this weekend, hanging out in the Los Angeles area.

The 26-year-old pop star recently completed three months of treatment at a rehab center following an apparent overdose in July at her Los Angeles home and an almost two-week hospital stay. The singer, who has battled substance abuse for years and has spent time in rehab before, went out for sushi in Beverly Hills on Saturday night with designerHenri Alexander Levy. The two were photographed in a car outside the Matsuhisa restaurant.

“Demi looked great and so happy to be out,” an eyewitness told E! News. “They seemed like good friends who were catching up and excited to see one another. There wasn’t any PDA or romantic gestures, but she was smiling and laughing throughout dinner. She was very relaxed and at ease. She said hello to the sushi chefs when they greeted her with a big smile. She seemed happy and healthy. They stayed for an hour and a half before leaving together in his car.”

In addition, several people tweeted that they spotted Lovato at Universal Studios’ Halloween Horror Nights on Friday night.

It is unclear if Lovato has completed her rehab stay and returned home or was just permitted to travel for the weekend.
