Demi Lovato breaks social media silence

Demi Lovato, who entered a treatment center following an emergency hospitalization for an overdose in July, and has since been more than 90 days sober, made an Election Day message her first social-media post since August.

"I am so grateful to be home in time to vote!" the singer-actress, 26, wrote on Instagram on Tuesday, alongside a photo of herself at a voting carrel. "One vote can make a difference, so make sure your voice is heard! Now go out and #VOTE!!!!"

Lovato, who has not commented on Twitter or Facebook since before the overdose, most recently had posted on Aug. 5, in a since-deleted message that said in part, "I have always been transparent about my journey with addiction. What I've learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet. . . . I now need time to heal and focus on my sobriety and road to recovery."

On Wednesday, TMZ.com reported, citing anonymous sources, that Lovato is spending four days a week in a private home and three days a week at a sober house with counselors and other recovering addicts. As well, the site said, she has a 24-hour sober coach and regularly attends AA meetings.

Meanwhile, on Sunday, TMZ.com posted a cellphone image of Lovato at a restaurant table for two, holding hands with a young, bleached-blond man identified as clothing designer Henry Levy, founder of the label Enfants Riches Déprimés. TMZ also ran photos by the agency Backgrid showing Lovato and Levy inside a vehicle leaving what the site said was the Beverly Hills restaurant Matsuhisa.
