It's a special moment for Demi Lovato and Wilmer Valderrama: the couple is celebrating their 6-year anniversary! We seriously can't believe that the pair has been dating for six years, but Demi took to Instagram to remind us of all of the amazing times they've shared over that span of time.
She posted a collage that shows photos from each year they've been together.
