Sting

Bruce Springsteen and Paul McCartney are each nominated for multiple 2013 Grammy Awards, and could put further strain on their already crowded trophy cases when the show airs tonight (Feb. 10) live on CBS at 8 pm ET/PT.

It will truly be a made-for-television moment when Sting hits the stage alongside pop stars Bruno Mars and Rihanna at the Grammy Awards on Sunday night. It's not clear what the motley trio will perform. The collaboration was revealed among the announcements of other Grammy performers on Monday.
