But if you're someone that prefers the black bondage, you're still in luck: Britney Spears rose up from the stage in a matching black patent leather leotard half-way through the performance, wearing a mask that made her look like a naughty Playboy Bunny searching for trouble.
While 'S&M' isn't nominated for any awards this evening -- RiRi's 'What's My Name? is up for Best R&B Song, though -- the single peaked at No. 1 and is currently No. 11 after 18 weeks on the Billboard Hot 100. Spears jumped on the remix to the 'S&M' only last month, marking the first collaboration from the two pop stars. So how do you end a performance where two of the hottest pop stars are dancing around suggestively on stage to the sound of whips and chains? With a pillow fight, of course.
Watch video of their performance after the jump.
