1991: Prince bares all

Clad in a yellow laser-cut lace tuxedo, the Love Symbol himself took to the VMA stage in 1991 to perform his air-lick of a single 'Gett Off.' As he gyrated through the song, Prince turned his back on the audience to reveal his ass cheeks to the world, covered in nothing but a light see-through mesh and exposed through a cut-out in the yellow costume. Thankfully he didn't take a bow.
