The ominous song, which the rapper also produced, is heavily influenced by the infamous crime couple Bonnie and Clyde. It's a recurring theme in Eminem's own music, specifically on 1999's "'97 Bonnie & Clyde." The pair embody different characters, with Grey promising to "kill for you" while Eminem is the manipulative, brainwashing half of the pair. "You always ride/Whatever the plan is/'Til the end/Even if I led us into an ambush," the rapper rhymes.
"Since the first day I started writing 'Kill for You,' I thought the Bonnie and Clyde message would be more powerful as a duet," Grey tells Rolling Stone. "I was stoked when Marshall put a verse on it."
Grey has worked as a collaborator and duet partner with Eminem in the past. She has co-writing credits on all three versions of "Love the Way You Lie" and appeared as a vocalist alongside the rapper's feature on Dr. Dre's "I Need a Doctor" as well as Eminem's own "Asshole."
