Rihanna’s gone and done it again. Not only did she score a hit with her single “S&M,” but now the singer is collaborating on an “S&M” remix with one of the biggest pop stars in the game – Britney Spears.

"In order to do a remix, it had to be major," Rihanna said during a Monday radio interview with Z100’s Elvis Duran and the Morning Show. "I asked my fans last week who they wanted me to collaborate with, and Britney was one of the most popular names."

What’s even hotter is that the pop divas may shoot a video for the sexy song. “I hope so,” Rihanna said. “I want to spank Britney.”

Britney’s appearance on the track marks the first time the 29-year-old has been featured on another artist’s song.
