We're only a couple weeks from revealing the nominations for the 54th annual Grammy Awards in a huge star-studded musical extravaganza that is set to air on CBS November 30th. While the roster to this point, which includes Jason Aldean, Lady Gaga, Ludacris, Sugarland, and Lupe Fiasco, would make for a pretty strong representation of music in 2011, more performers have been added.

Pop diva Rihanna, country group The Band Perry, and r&b superstar Usher are the latest artists to secure a spot on the Grammy Nomination Concert Live!. Rihanna, who will be releasing her next album Talk That Talk a week prior, has won 4 Grammys in her short career, including last year's Best Dance Recording for "Only Girl (In the World)", and could score nominations from the track's parent album Loud this year. The Band Perry recently celebrated three CMA wins to go along with the one year anniversary of their debut album, so gaining a spot on the nomination special could give them an extra push toward garnering some nominations, including Best New Artist. Seven-time Grammy winner Usher has only released or been featured on a handful of singles within the eligibility period.

The 54th annual Grammy Awards will air Sunday, February 12th, 2012 at 8:00 on CBS.

Which of the three new additions are you most looking forward to seeing perform? How many nominations will Rihanna and The Band Perry rack up? Who do you think will walk away with the most nominations overall?
