Ariana Grande and The Wanted's Nathan Sykes released their video for Almost Is Never Enough, a love ballad from the soundtrack of The Mortal Instruments: City of Bones.

Throughout the video the two are seen singing their hearts out in a studio. Grande sports a white dress and wears her hair in a half-up half-down look while Sykes keeps it simple in a plain white buttoned-down shirt. The stars also flirt with each other and end the clip with a big hug.

"Almost, almost is never enough, so close to being in love. If I would have known that you wanted me the way I wanted you, then maybe we wouldn't be two worlds apart but right here in each others arms," they sing.

Scenes from the film are also featured in the video. The movie is set in New York City and is based on a book series written by Cassandra Clare. It follows the life of teenager named Clary Fray (Lily Collins) who discovers that she is a Shadowhunter - a half-angel warrior who has to protect Earth from demons. After her mother disappears, the young girl is forced to join other Shadowhunters and enters the Downworld, which has dangerous and violent creatures.

Clary's mother is played by Lena Headey. Other actors in the film include Jamie Campbell Bower, Jonathan Rhys Meyers and Kevin Zegers.

"I'm so excited! I had read and really loved the books," Collins told Glamour's June 2013 issue about starring in the film.

With the fan anticipation for the film mounting, Collins also said she doesn't want to let them down.

"The fans [in Toronto, during filming] were amazing. They'd bring us cookies, mugs, tea, drawings, everything. I want to make sure I live up to their expectations as Clary," she said.

The Mortal Instruments: City Of Bones comes to U.S. theaters on Aug. 20.
