Rihanna and Usher to Perform at Grammy Nominations Concert

The stars keep coming! Rihanna and Usher are slated to perform at the annual Grammy Nominations concert. The single-named superstars will take the stage on Nov. 30 in addition to many other acts.

The stars will perform live from the Nokia Theatre in Los Angeles along with five-time Grammy winner Lady Gaga, three-time winner Ludacris, winner Lupe Fiasco, two-time victors Sugarland and country star Jason Aldean (who will likely get a nod himself). Two-time Grammy winner LL Cool J serves as the event's host for the second year in a row -- and he's also a producer of the show.

Rihanna and Usher are no strangers to the Grammy stage. Rihanna has four of the awards to her name, and Usher has a whopping seven under his belt!

In addition to the stellar performances, the event will reveal the top nominations for the 2012 54th annual Grammy Awards. The show will air live on CBS on Nov. 30 at 10PM EST.
