Eminem revealed the news via Instagram, updating his account with two images from the set of the video.
In one image, Eminem sits beside Rihanna, with both artists wearing all black. In another image, Eminem revealed that the video's director is Rich Lee.
Rich Lee has been the director of other Eminem videos, including "Not Afraid" and the clip for the Bad Meets Evil single "Lighters." Lee also directed the Eminem-assisted "My Life" video for 50 Cent, which also features Adam Levine. Beyond this, Lee has also directed videos for The Black Eyed Peas and Diddy.
Rihanna spoke about working with Eminem during a January interview with Complex.
"The moment I worked with him on 'Love the Way You Lie,' I wanted to work with him again, and we did 'Love the Way You Lie Part 2,'" Rihanna said. "And then I wanted to work with him again. I just love working with Eminem. He’s just one of my favorite rappers, and his lyrics—he’s a true poet, and I enjoy that about him. For this song, I needed someone with not only his skill, but his personality. And I needed someone who really understands the perspective and the metaphor in the song of going numb and being numb to everything around and to say, 'Fuck you.' Eminem is definitely the perfect guy for that."
Earlier this month, Eminem spoke about Rihanna's work on "The Monster."
"The perception of the record, what it's saying, I thought it would be a good idea to have her on it because I think people look at us like we're both a little nuts," Eminem said during an interview with SiriusXM radio station Shade 45. "That's one of the things that I was telling her in making the record: I think that people look at us a little crazy."
