The trailer for the film where Machine Gun Kelly and Megan Fox's romance first began has arrived.

The movie, titled Midnight in the Switchgrass, stars Fox and Bruce Willis as FBI agents hunting down a serial killer who preys on young women. Kelly, who also has a role in the film, started dating Fox after they met on the set.

In the trailer, which premiered via Entertainment Tonight, Fox's character is used as "bait" to entice someone related to the case, played by Kelly. The scene begins with him trying to have sex with her in a dingy motel room, and ends with her punching him in the face.

Midnight in the Switchgrass premieres in theaters and on-demand July 23.

Kelly, who's credited under his birth name, Colson Baker, has previously acted in movies including Beyond the Lights and Bird Box, and played Tommy Lee in the Mötley Crüe biopic The Dirt. He also, of course, starred in Downfalls High, the musical film based on his new album, Tickets to My Downfall.

You can catch a preview of Kelly and Fox's acting chemistry in the video for the Tickets lead single, "Bloody Valentine."
