Watch Demi Lovato marry Jesse Williams

Demi Lovato and 'Greys Anatomy' star Jesse Williams play lovers in the singer's new music video, 'Tell Me You Love Me'.

The 25-year-old teased a picture of herself wearing a wedding dress on Instagram a week ago, which led to her 63-million followers speculating about what she was up to.

While many guessed the image was for a music video - adding hunky actor Jesse to the mix came as a pleasant surprise to her fans.

The 6:47-minute long video features a two-minute intro about the on-screen couple's rocky relationship.  

Jesse proposes to Demi at the beginning of the video, but will they say their "I do's" by the end of it?

"It's possible we're not ready," Jesse says before the video starts.

"We're ready. I've never been more ready," an almost desperate looking Demi assures him.
