Rick Rubin is one of the founding members of Def Jam and has worked with some of the biggest tastemakers in Hip-Hop, including Eminem, the Beastie Boys, and Kanye West. Now it seems that the legendary producer is working with Justin Bieber on new music. 

The pop star uploaded a photo of himself hanging with Rick, which he captioned, "With the man Rick." Insiders told TMZ that Justin is looking for an "urban" sound on his new album, and the Canadian native believes Rick is just the person to help him out.
