Detroit, MI – Eminem and Snoop Dogg are rarely in the same city at the same time. But considering Snoop is in Em’s hometown of Detroit this week, the D-O-Double-G was able to pop in on Slim.

On Wednesday (October 24), Snoop shared a photo of the two rap titans in the studio together, both with mischievous smiles on their faces.

“Detroit. Tommoro. 8 pm. Redemption of a Dogg,” he wrote in the caption. “had to c M. To get the stamp.”

Snoop is referring to his Redemption of a Dogg stage play starring Tha Doggfather, Tamar Braxton, Omar Gooding and Eric Benet, among others. The show’s three-night run at Detroit’s Music Hall kicks off on Thursday (October 25).

Less than 12 hours later, Snoop posted another photo of himself in the studio with Em and Denaun Porter.

The caption read simply, “Squad. 8 mile.”

The photos quickly sparked rumors of a collaboration. Snoop and Em have never released an official single but Snoop was a featured guest on The Marshall Mathers LP track “Bitch Please II” in 2000.
