Listen: Britney Spears & Rihanna Debut 'S&M' Remix

Grab your whips and chains because Rihanna and Britney Spears are joining forces. On Monday morning, singing powerhouses Rihanna and Britney Spears launched their collaborative "S&M" remix on Z100's "Elvis Duran and the Morning Show." There's so much much pop power in this saucy, 4-minute remix -- you can hardly stand it!

Rihanna explained the reasoning behind choosing "S&M," "At first, we didn’t know what the song was going to do because of the lyrics, but it became really big on radio and it's No.1 at Pop this week. In order to do a remix, it had to be major. I asked my fans last week who they wanted me to collaborate with, and Britney was one of the most popular names."

Britney has been heating up the charts with her new Femme Fatale album, just as Rihanna has been setting the music world ablaze with Loud, her fifth studio album.

"It's very strange. Britney never does features. It was really amazing that she really wanted to be part of this song, "Rihanna said of the opportunity to work with the chart-topping femme fatale. "She really liked the song to begin with, but it was a different story when she had to sing it, and she really wanted to be a part of it. It made it really special, because you never see two pop female artists doing songs together anymore. Just call us R&B."
