Eminem surprised the crowd at Drake's concert Tuesday night at Joe Louis Arena.
The hometown rapper emerged from under the stage in the middle of the show.
Drake bowed to Eminem, calling him the 'greatest rapper to ever get on a microphone.'
"It's an honor to share the stage with this man right here," Eminem responded.
