It's so good being bad when you are Britney Spears and Rihanna, two of the sexiest princesses in pop music.

The duo took to Twitter yesterday to reveal that they have teamed up for a remix of RiRi's dirty girl anthem 'S&M’ and it blazes hotter than a photo of these two in their skimpiest, tightest outfits! Grab a fire extinguisher when you listen to this one, because it'll burn!

The remix adds Brit's breathy vocals over top Rihanna's impassioned singing and a beat that just won't quit. You will like it, like it, like it, come on!

The references to whips, chains and sex-citement -- it's almost too much in one remix. This uber sexy double teaming will set the hearts of any red-blooded American man on fire.

Rihanna tweeted about the partnership on Sunday, posting: "I got a #SEXY collabo comin your way supa dupa soon!!!! OH YEAH!!! By popular demand…it's Britney bitch!!"

"You're such a tease! I like it, like it…." Brit tweeted in reply.

Brit Brit and RiRi are such teases! Do you feel your temperature rising? Your skin perspiring? Your heart racing?
