Singer-actress Demi Lovato has been photographed in public for the first time following her most recent rehab for what her mother has confirmed was an overdose.

TMZ.com on Sunday posted a series of photos including a cellphone image from inside a restaurant showing Lovato, 26, sitting at a table for two and holding hands with a young bleached-blond man the website identified as clothing designer Henry Levy, founder of the label Enfants Riches Deprimes, as well as photos by the agency Backgrid showing Lovato inside a vehicle with Levy. TMZ said the two were leaving the Beverly Hills restaurant Matsuhisa, flagship of chef Nobu Matsuhisa's culinary fleet, on Saturday night.

At least one Twitter user said he had spotted Lovato at Universal Studios' nearby theme park the same evening. "@ddlovato just walked past us at Halloween Horror Nights looking healthy as ever. heard she’s almost 100 days clean," the commenter said, adding a hands-in-prayer emoji. He added, "She seemed happy! waving at people and smiling," and that she was accompanied by "1 guy and 3 security."

She had been photographed outside her Los Angeles rehab facility on Sept. 23 on what TMZ called a day pass. Standing with coffee cup in hand, she chatted with an unidentified woman walking a dog.

Lovato, who has not commented on social media, has been candid about past treatments for an eating disorder, cocaine addiction and bipolar disorder. On July 24, she was transported from her home in Los Angeles' Hollywood Hills neighborhood and admitted to Cedars-Sinai Medical Center with what her mother Dianna De La Garza in an Oct. 26 podcast called "an overdose."

De La Garza additionally told the program, "Conversations with Maria Menounos," that Lovato was 90 says sober, adding, "I couldn't be more thankful or more proud of her because addiction, being a disease, it's work. … It's very hard, it’s not easy, and there are no short cuts."
