Eminem is a pretty reclusive guy.
But we can't say we are too surprised that Em left his home in Detroit to "surprise" the crowd at 50 Cent's show in The Motor City last night.
Shady rapped his verse on "Patiently Waiting" and "Crack A Bottle" for the fans at the Pine Knob Music Theatre.
He also had some kind words for Fif.
“Detroit, make some noise for one of the best friends that I’ve ever known, 50 Cent!” he yelled to the crowd “And also, make some noise for Hip Hop’s 50th birthday, y’all … Detroit, I love y’all, man.”
50 Cent returned the favor.
"Bro when I do anything with EM people just go crazy they know he really my boy. I love him till death," 50 captioned.
