The show before the show is already shaping up to be pretty massive. On Wednesday (November 10), the folks behind the Grammy Awards announced the lineup for the "Grammy Nominations Concert Live" show on December 1, which will feature appearances from such Grammy newbies as Justin Bieber, B.o.B and Bruno Mars.

Joining the fellas on the show will be Katy Perry and country star Miranda Lambert. Rapper LL Cool J will again host the one-hour affair from the Club Nokia in Los Angeles. More performers and announcers will be announced shortly for the third nominations special from the Grammy organization.

The 53rd Annual Grammy Awards will air live on CBS from the Staples Center in Los Angeles on February 13.

Before that though, the 11th annual Latin Grammys will take place on Thursday night, November 11, with performances by Marc Anthony, Enrique Iglesias and Nelly Furtado. Ricky Martin will be on tap to present the 2010 Latin Person of the Year award to opera great Placido Domingo.
