Rapper Big Sean posted a photo of himself with Eminem in the studio on his Instagram in April, which hinted that the two were making music together.
Now, the G.O.O.D. Music rapper spoke about the collaboration.
"People can expect a Detroit classic," Sean told MTV News in an interview published on Friday.
The 25-year-old, who was raised in Detroit, also said how surreal the opportunity to work with Eminem felt.
"Being in the studio, I just remembered when my mom bought me his [first] album from Costco or something a long-a-- time ago, so you could just imagine going from that moment - being a lil-a-- boy - then fast forwarding 10 years later and being in the studio with him," he recalled.
Despite their 15-year age difference, Sean and Eminem discovered that they both share similar life experiences, Sean said.
"It was tight. We talked for a few hours before we even worked on music. I was telling him my stories about how we were performing all around downtown Detroit and [it turned out that] he was performing in the same places," he said.
Finally, Sean told MTV News that the song could end up on either his upcoming sophomore album or on Eminem's eighth studio album.
"You might get it from my album, you may get it from his album, you may get it a little later," he said. "We've got to work all that out."
Sean's second album titled Hall of Fame is expected sometime this summer, and will feature appearance by Nas, Miguel and Jhene Aiko.
Eminem's album, on the other hand, has yet to have have a confirmed release date. All that's known is that the album will surely be released in 2013. Eminem also invited Chris Rock to join him in the studio, as the comedian revealed on his Twitter page on May 7. In addition, he was in the studio with Kendrick Lamar on Wednesday.
