Listen to Big Sean on iHeartRadio | Listen to Eminem on iHeartRadio

Detroit's two biggest rappers are hitting the studio together.  Over the weekend, Big Sean took to Instagram to post a picture of himself and Eminem in the recording studio together. 

While it's not known whether the pair were actually collaborating on a track together, Sean certainly wanted fans to know that having Em in the studio with him was a milestone in his career.  In a caption accompanying the photo, Sean writes that "today was historical."  

Big Sean recently hinted that a collaboration with Eminem could be in the works.  While he wouldn't confirm whether Eminem would appear on his upcoming album "Hall of Fame," Sean told a Washington, D.C. radio that a collaboration with Eminem will happen "sooner or later." 

Big Sean plans to release Hall of Fame sometime in June.
