(AllHipHop News) Hip Hop legend Snoop Dogg connected with Pharrell Williams to provide the soundscape for his latest LP Bush, but it appears the Long Beach rapper has reunited with his original production partner Dr. Dre. Snoop posted a picture to his Instagram page of him and the Good Doc together in the studio.

The caption for the photo only reads, “Guess who bacc [sic],” so it’s not clear what the two West Coast icons may have been working on. It could be something for a future Snoop project, or perhaps Dre tapped his frequent collaborator for the possible Straight Outta Compton movie soundtrack.

The duo previously got together for the rap classics “Deep Cover,” “Nuthin’ But A ‘G’ Thang,” and “Still D.R.E.” Snoop appeared throughout Dre’s Hip Hop masterpiece The Chronic, and Dre also produced Snoop’s 5x platinum debut album Doggystyle.
