This was most likely staged, but here's a clip of Sacha Baron Cohen (as his character Bruno) dressed as a white dove, flying over the audience and, well, basically landing on Eminem's face.
Damn, Eminem, your sour pouty face is even more butt ugly now. I saw the trailer for Bruno a few times this weekend 'cause I went to see Drag Me To Hell twice. Patron of the arts, they call me.
