Looks like Rihanna, Usher and the Band Perry can count on some Grammy nominations this year -- all three acts have been added to the lineup of this year's Grammy Nominations Concert Live!, the CBS primetime special that will reveal the nominees in the top categories.  The show, which airs November 30 at 9pm will also feature performances from Lady Gaga, Ludacris and Lupe Fiasco, plus country stars Jason Aldean and Sugarland. Actor and Grammy-winner LL Cool J hosts the show.

In addition, CBS says the Grammy Nominations Concert Live! show will feature a special "live announcement regarding a historic band reunion set to take place on the Grammy stage in February 2012."  It's widely assumed that this announcement will about Van Halen, who are reportedly reuniting with original lead singer David Lee Roth to make a new album.  I love Van Halen, and I sincerely hope that is true!
