Eminem and Rihanna recently have reunited for their collaboration off chart-topping "The Marshall Mathers LP 2," and the duo is now getting ready to unveil the music video for "The Monster."

Slim Shady took Instagram to post up two photos he took on the set of the video shoot, letting his fans and followers know that the production of music video is now in progress. One of the snaps features the Detroit rapper sitting beside the "What Now" singer, both clad in all black. Another image reveals Rich Lee as the director of the visual.

Rich Lee has been Eminem's favorite director: he has worked on the music videos of the lead single "Not Afraid" from Eminem's 2010 "Recovery" album and the Bad Meets Evil single "Lighters." He also directed Eminem-assisted "My Life" video for 50 cent featuring Adam Levine.

Eminem has previously collaborated with the Bajan singer on "Love the Way You Lie" off "Recovery," the sequel "Love the Way You Lie Part 2" from Rihanna's "Loud" album and the most recent "Numb" from her "Unapologetic" album last year. Earlier this year, the self-claimed "Rap God" spoke about Rihanna's work on the current hit single, "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," said Eminem. "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."
