Kendrick Lamar and S**op Dogg are hard at work on their own respective albums, and it appears there may be some collaboration being done between them. S**op Dogg posted on his Instagram a simple photo of him and fellow West Coast representative K. Dot in the Studio with the caption "Work." It is **t clear what they are working on, but speculation says it could be a feature on S**op's upcoming album "Bush" that is being produced by Pharrell.
