Big Sean has talked about collaborating with his fellow Detroit emcee, Eminem, for quite some time now. It looks like the two finally locked in studio time together alongside Royce Da 5'9", not to mention, Big Sean also got some solo time in with Royce Da 5'9".

Photos surfaced on Instagram today of Em, Sean Don and Royce in the studio together. As well, yesterday, Big Sean and Royce hit the studio with D12 member/producer Denaun Porter.

Big Sean's Hall of Fame album arrives later this year, and he's hinted at an Eminem collabo for the LP, so we'll have to wait and see what happens. Eminem also is reportedly working on an album for later this year.
