Grammys: Rihanna To Perform With Bruno Mars & Sting

The 2013 Grammys are fast approaching, and the list of performers is still growing: Last night via Twitter, the awards show announced that crooner Bruno Mars and the legendary Sting will join Rihanna onstage for a special performance.

So what will they do together? What will they sing? Our prediction is that Rihanna, clothed in a Lanvin onesie, Kenzo trucker hat and a garland of rose petals, will emerge triumphantly from a trapdoor while Sting sings “Desert Rose” and Bruno Mars tap-dances on the corner of the stage wearing a fedora. Another possibility is that Bruno Mars and Sting will be tied and gagged wearing bondage gear in cages on the stage while the Bajan pop princess sings “S&M.” But that’s just a few ideas. As the great Ellie Goulding once famously noted, anything could happen.

In case you missed, @brunomars @rihanna + Sting (@officialsting) will be performing together at the 55th #GRAMMYs next Sunday on @cbstweet!

Rihanna is up for three Grammys this time around, while her fellow nominee Bruno is up for one. (Sting, of course, already has a tantric sex closet full of them at home.) The live broadcast will air this Sunday, February 10th, at 8:00 p.m. EST on CBS.
