G.O.O.D Music’s Big Sean may have something brewing with fellow Detroit native Eminem, revealing a photo of himself and the Shady Records head this week.

Although details are still slim, Sean sparked some anticipation for an Em collaboration.

“Today was historical http://instagram.com/p/YlZpfDj2tT/,” Sean tweeted Friday (April 26), with an Instagram shot with him next to Em. (Big Sean’s Twitter)

Recently, Sean said fans could possibly see Slim Shady appear on his upcoming Hall of Fame album.

“Nah, I can’t confirm it,” Sean said in an interview when asked about a Slim Shady record going down. “But he may be on there. I’m pretty sure you’ll get an Eminem/Big Sean collab sooner or later. Whether you get it on Hall Of Fame, whether you get it after Hall Of Fame, [I’m] pretty sure you’re gonna get something.” (The Urban Informer)

Last month, the rapper said he did not have the Em record secured just yet.

“The album’s really good, it’s really heartfelt, I feel like the [Detroit] mixtape set the tone and the album is going to take it to the top. … Miguel’s on the album, for sure, it’s a lot of good people on the album,” Sean promised in an interview. “I can’t say Eminem’s on there. He’s not on there right now, as of now.” (DDS)

Back in November, Sean spilled the beans on Marshall Mathers reaching out to him.

“Em didn’t come to the [‘Guap’ music] video. Em didn’t come but let me tell you something man,” Sean said in an interview with radio personality Tim Westwood. “Em reached out to me and was like, ‘Come to the studio. Come hang out when you get a chance. We gonna make that happen, man. That’s the legend right there.” (“Tim Westwood TV”)
