We're thrilled to see her happy and healthy!

Demi Lovato has completed three months of rehab following her July overdose, and it looks like she picked up a new boo in the process!

Photographers caught the singer on a sushi date at Matsuhisa in LA with clothing designer Henry Levy over the weekend, and the two were holding hands at the table. We guess this means she isn't getting back with supportive ex Wilmer Valderrama?

Her new man has been open about his own struggles with addiction, so let's hope they can be good influences on each other and keep each other sober.

"Demi is doing great and is really receptive to the help that she is getting. Treatment has really changed her and she is looking forward to remaining sober and her new outlook on life," a source dished to E! News.

We love a comeback story!
