One of Big Sean’s dreams came true when he hit the studio with his idol Eminem on Friday. It’s unknown if the Detroit rappers were working on a collaboration, but Sean shared the special moment with his fans.

“Today was historical,” tweeted the G.O.O.D. Music MC.

Earlier this year, he spoke about his plans to play Em his sophomore album Hall of Fame.

“I wanted to make sure my album was completely done before I went and played it for him,” Sean told Rap-Up TV. “I know a while ago he reached out.”

Hall of Fame is due this summer featuring collaborations with Miguel, Jhené Aiko, Nas, and more.
