Demi Lovato and Jesse Williams are having a fairy tale moment!

The 25-year-old singer cast the Grey's Anatomy star to play her love interest in the new music video for "Tell Me You Love Me," the latest single off her sixth studio album of the same name.

The video, shot in Los Angeles and directed by Mark Pellington, shares the story of a couple going through all the ups and downs of a relationship. From sweet kisses to the exciting proposal to jealousy to wedding day, Lovato and Williams act out all the pivotal moments in this sexy, cinematic video.

While the video is entertaining from beginning to end, our favorite moment occurs at the 4:52 mark, when Lovato and Williams tie the knot in a stunning outdoor ceremony:

"This song is one of my favorites which is why I named my album after it," Lovato said in a statement. "I not only love singing it, but I think the underlying meaning is important for people to know. At the end of the day, you have everything you need standing right in front of you. And that's yourself."

"Shooting this video was really fun, too!" she continued. "We had a full-on wedding and my best friends were even my bridesmaids and groomsmen. The locations were absolutely beautiful. It was perfect."

Lovato teased the video was coming last month when she posted a captionless picture of herself wearing a wedding gown to her Instagram and Twitter accounts.

When ET caught up with Lovato in November, she got candid about her romantic life, revealing why she's taking time to "find" herself. 

"I think I found her, and I think I'm still finding her," she explained. "And that's why I'm not diving into anything with anyone. I value my time by myself now, and I value my time with my friends. And I just have learned to really appreciate my me time and getting to know myself and learning to fall in love with myself before I fall in love with anyone else."
