See Latex-Clad Rihanna, Britney Spears' Pole Dance, Pillow Fight

They may be bad, but they're perfectly good at it!

At Sunday's Billboard Music Awards, Rihanna teamed up with Britney Spears onstage for a live rendition of their sexy "S&M" remix duet.

And Rihanna, 22, and Spears, 29, didn't disappoint fans performing the bondage-themed pop smash. Both clad in latex bodysuits (Rihanna in white, Spears in black) the duo writhed on the floor, pole danced, brandished whips and chains . . . and engaged in the sexiest pillow fight ever!

Watch the kinky duet now.
