Did Wilmer Valderrama & Demi Lovato Share A Halloween Hookup?

By Michael Lopez

Time to break out the microscopes! Demi Lovato tweeted a very interesting picture this past weekend that may or may not have a celebrity guest in it. Shot at a L.A. Halloween party, the photo shows Lovato, two friends, and someone who looks a lot like Wilmer Valderrama!

Demi, who still claims to be single, has been linked with Valderrama for months now. They first supposedly started dating in January (right after she broke up with Joe Jonas), then cooled it down by early summer.

But now, it looks like the romance is back on! Or at least it possibly is. Several gossip bloggers are still unsure whether or not the mysterious Latino in the background is Wilmer.

So far, both camps are staying mum on the picture. But upon closer inspection, it sure looks like Valderrama to us. Unless it's that mischievous web star, Eduardo Fresco!

Do you think it's Wilmer in the twitpic? Sound off in the comments or @MTV3.
