Eminem joins label pals Black Hippy and Royce Da 5'9 in the studio.
Close label proximity may be bringing two of Hip Hop's most lyrical camps close together.
The Black Hippy crew was in Detroit for their good kid, m.A.A.d city tour, where they met up at Em's studio:
Eminem and Kendrick are both under the Interscope and Aftermath umbrellas, with their respective compatriots attached via other deals.
Though it is not known whether Shady and Kendrick's crews collaborated, Eminem is currently wrapping up his eighth studio album.
Recently, Em and Royce were accompanied in the studio by fellow Detroit natives Mr. Porter and Big Sean.
