Rihanna, Sting and Mars to perform at Grammys

So a Bajan dance-pop femme fatale, a neo-Motown crooner and a bass-wielding British titan of tantra walk into a bar ... or rather, onto the Grammys stage ion Sunday.

CBS announced on Monday that the unlikely collaboration of Rihanna, Bruno Mars and Sting is the latest addition to the telecast set for this Sunday. Kelly Clarkson, fresh off her well-received (and live) performance at President Obama’s inaugural, will also perform her own set.

There’s no news as to what the trio will perform, but they will certainly make for an unorthodox stylistic mashup. |

The group joins a wide slate of confirmed Grammy performers including the Black Keys, Taylor Swift, Justin Timberlake, Frank Ocean and Elton John. Also added to the telecast as a presenter? Beyonce, who, after reuniting with Destiny’s Child at the Super Bowl and generating enough heat with her performance, possibly caused a power outage at the Superdome. The Grammys will held on Sunday night (Monday in the UAE) in Los Angeles.
