The couple dated for six years before heading their separate ways, however now, it looks like they could be back on.
TMZ caught the pair having a cozy lunch together over the weekend, with eyewitnesses saying that they were very friendly together, having a great time in each other's company.
Demi addressed breaking up with Wilmer during her Simply Complicated documentary she released last October. In it, she admitted that she still cared for Wilmer and probably always would.
"I've never loved anybody like I loved Wilmer and like, I still love him," she revealed. "We connected on a level that I've never connected with anybody before. He was just my rock. My everything."
She even explained how hard it was for her to be away from him. "I do have moments where it's late at night and I'm lovely and I wonder if I made the right decision, because love is a gamble. I don't know if I'll lose him for the rest of my life."
Well, it looks like Wilmer has always been there for her <3
