About a month ago, Demi Lovato got out of rehab, where she was being treated for “emotional and physical issues,” or so her rep says. We’ve never really gotten hardcore details about what was up with Demi, but I suspect it was a combination of old-fashioned exhaustion, drug and/or alcohol abuse, an eating disorder, plus a host of psychological stuff that is pretty common with girls that age. Anyway, the last time I saw photos of Demi (earlier this month), she looked healthy. She was headed into some facility for what everyone assumed was out-patient treatment for the eating disorder. Since she got out of rehab, she’s been keeping a lower profile, which I thought was good. But now I’m wondering. Us Weekly reports that Demi has been “meeting up” with her ex, Wilmer Valderrama. Wilmer was Demi’s boyfriend just before she went crazy – my guess is that he screwed with her mind too, like he tends to do with whatever jailbait he can get his hands on. And now she’s hanging with him again. UGH.

Demi Lovato is getting by with a little help from her friends — and a boyfriend. Since checking out of a treatment facility in late January, the Disney starlet, 18, has been meeting up with ex Wilmer Valderrama, a source confirms to UsMagazine.com.

PerezHilton.com also reports that the pair have been spotted out and about — and looking “affectionate” — catching movies and buying groceries in the L.A. area.

According to another insider, Lovato, 18, and the From Prada to Nada actor, 31, had been quietly dating since her May 2010 split from Joe Jonas. Lovato’s rep told Us on Wednesday, “We don’t comment on her personal life.”

Back in November, Lovato pulled out of her Camp Rock 2 tour with the Jonas Brothers to “seek medical treatment for emotional and physical issues,” her rep said at the time. In the past, the young actress and singer has battled eating disorders and self-mutilation.

“For now, she is getting back to her regular routine and spending time with her family and close friends,” a Lovato source told Us shortly after her rehab exit.

A Hollywood star since his days on That 70s Show, Valderrama’s ex-girlfriends include Mandy Moore and Lindsay Lohan.

Wilmer is a stone-cold predator, I swear to God. He’s worse than John Mayer, even. With Mayer, his douche is offensive and sleazy, but he’s not doing any real discernable damage. Wilmer is truly doing damage to very young, vulnerable young women. Because he only dates young, vulnerable women, exclusively around the age of consent. You know why? Because if Wilmer ever slept with an older girl who was more experienced sexually, the girl would realize really quickly what a psycho he is. In my mind, he’s a pencil-dicked predator who thrusts three times and then says something about the girl being “fat”. That sounds right, doesn’t it?
