Listen: Britney Spears and Rihanna collaborate on 'S&M' remix

They promised a collaboration, and just 24 hours after Rihanna and Britney Spears tweeted about teaming up for a remix of RiRi's single "S&M," the pop divas delivered big time.



It's definitely hot -- gotta hand it to BritBrit for holding up against Rihanna's strong vocals. Does this mean Rihanna could turn up for surprise appearances on Spears's upcoming tour? Anything's possible.

For those of you who can't listen at work, some of the song's more memorable lyrics:

I may be bad, but I'm perfectly good at it
Sex in the air, I love to the smell of it
Sticks and stones may break my bones,
But whips and chains excite me.
