Eminem and Skylar Grey have a pretty solid track record, after collaborating on Grey’s “C’Mon Let Me Ride,” Dr. Dre’s “I Need a Doctor,” and Em’s Rihanna-featuring “Love the Way You Lie,” which Grey cowrote. Now, the pair have reunited yet again for “Kill For You,” a foreboding duet inspired by Bonnie and Clyde.

Grey delivers impassioned declarations of ride-or-die love for her man, promising, “I’ll carry out his evil plans if he wants me to.” Em, meanwhile, is the master manipulator of the two, admitting he “brainwashed” his girl and telling her, “I’m your alternate escape route, the altar you pray to / Your ultimate savior, your behavior is altered.” The song (which Eminem also produced) begins with sounds of running footsteps, slamming doors, and ringing alarms, and ultimately ends with one ominous gunshot. Uh-oh.

Grey told Rolling Stone about the track, “Since the first day I started writing ‘Kill for You,’ I thought the Bonnie and Clyde message would be more powerful as a duet. I was stoked when Marshall put a verse on it.” (Yep, you know they’re tight when she refers to him by his legal first name.)

“Kill for You” appears on Grey’s third album, Natural Causes, which drops tomorrow (September 23).
