There are sure to be some surprises on Big Sean’s highly anticipated sophomore album Hall of Fame and one of those surprises could be an Eminem placement.

The G.O.O.D. Music rapper was seen in studio with Eminem, Royce Da 5’9 and Denaun Porter from Instagram photos posted recently. Sean and Royce collaborated before on the track “100” from the Detroit mixtape.

Big Sean recently told Tim Westwood that Eminem had invited him to the studio and now apparently the two have finally linked.

In the main picture featuring he and Em, Sean captioned the photo as “Today was historical.”
