While we heart Demi Lovato and want to see her happy, we're sort of hoping this isn't true, just because he's so skeevy -- but she and Wilmer Valderrama may be back together.

The pair were last photographed together on Sept. 12, but they've been friends since before they dated, so no one was quite sure what to make of it. However, they were spotted getting cozy in a photo from the 'X Factor' set. The pair posed with Paige Thomas, one of Lovato's team members, with Valderrama's arm around Lovato. Of course, he may well have just been posing for the photo that way, but since the two of them have quite a history, we're keeping our antennae up.

We're not a huge fan of Valderrama, since it seems like he hurt Demi previously -- at least based on her cryptic tweets around that time -- then went and got all BFFed up with Joe Jonas, who also broke her heart. Plus, there's the age thing. He's 32, she's 20, and they started dating when she was 19 and he was 31. A little weird, right?

In any case, a source told Hollywood Life that it's not the first time Wilmer's been lurking around the set -- and that a reconciliation with Demz, if it hasn't happened already, is pretty inevitable. “They are not officially dating but it’s only a matter of time," the source said. "They really have always liked each other, still have tons of respect for each other, and are still in love.” Yeah, but we say she can still do better -- but whatever floats her boat, right?
