Jesse Williams leaves Demi Lovato at the altar in heartbreaking music video

After weeks of lace-filled teasers on social media, the singer premiered the clip for her sixth studio album‘s title track on Friday morning. Featuring Grey’s Anatomy‘s Jesse Williams proposing with a huge diamond, the clip transports viewers to a picturesque wedding day with happy guests. One problem: This is a tense relationship defined by fights, jealousy, and deep insecurities. Nope, there are no happy endings here. Right before “I do,” Williams takes off his wedding ring and walks back down the aisle.
