Here we go again: X Factor judge Demi Lovato and on-again, off-again boyfriend Wilmer Valderrama continue to send mixed messages (literally) on whether or not they’re back together. They’ve gone from doing super cute couple things like furniture shopping and supporting each other online to spending weekends apart chatting up exes.

This past weekend, Wilmer jetted off to Las Vegas and shared a photo of him surrounded by bodacious waitresses at local hotspot Blondies. As if that wasn’t already suspicious, Wilmer hit the club with, believe it or not, Demi’s ex, Joe Jonas. Were they swapping dating tips or pairing up for a night of DemDem-free fun? Either way, things for our wannabe celeb couple didn’t look good.

Then, just as we’re deleting our list of Demi/Wilmer couple names (top pick: Wilmi), the boy tweets, “To whom it may concern” with a pic of number 143 (you know, how the cool kids say “I love you” nowadays). Could this be for Dems?

We like to think so since the pair seemingly can’t get enough of each other, between making out on Valentine’s Day to hanging out on the set of the X Factor.

What do you think? Is there any hope for these two crazy kids to finally make it work? Sound off below.
