Chris Rock has been known to appear on Hip Hop albums, as he lended his comedic talents to Kanye West for "Blame Game" in 2010.
Most recently, Chris Rock was spotted in the studio with Eminem. It's not clear what exactly they were working on, but knowing Em's humor, hopefully the two are putting together something hilarious.
