What is Eminem cooking up in the studio? According to his manager Paul Rosenberg, he's definitely going to drop an album this year. And he was recently spotted in the studio with Big Sean and Royce da 5'9", even though it wasn't clear what they were working on.

Now, Chris Rock has joined the fray. Earlier this week he tweeted about working with Marshall and also posted a photo of them together on Instagram.

Some of his best stand up material is about rap, including a bit about defending rap music.

We can only hope they come up with something as funny as this:
