Lupe Fiasco, Ludacris Added To Grammy Noms Concert

Lady Gaga and country artists Sugarland, Jason Aldean also set to appear at November 30 event in Los Angeles.

Ludacris, Lupe Fiasco and country duo Sugarland have been added to the lineup for the annual "Grammy Nominations Concert Live!!" (two exclamation points because it's just that exciting), set to air November 30 at 10 p.m. ET/PT on CBS.

They join a list of performers that already includes Lady Gaga and country singer Jason Aldean, with LL Cool J once again serving as the master of ceremonies. In addition to the performances, nominees will be announced in several Grammy categories and, according to a press release from the Recording Academy, the show will also feature "a special, live announcement from a truly iconic group regarding their historic band reunion," set to take place at the upcoming Grammy Awards. (The ceremony will air live from the Staples Center in Los Angeles on February 12 on CBS.)

While we can only speculate about just who will be doing the reuniting (classic Van Halen?), in recent years, an onstage reconciliation has become nearly as much a part of the Grammy telecast as the golden gramophone award itself, as everyone from Blink-182 to the Police have used the event to bury the hatchet and launch comeback tours.

And though we won't know all of the nominees until November 30, presumed frontrunners include Adele, whose 21 not only features two of the year's biggest singles, but is also the year's best-selling album; Katy Perry, who continues to string together an impressive series of hits; Rihanna; and Lady Gaga, all of whom have also dominated 2011.

"The Grammy Nominations Concert Live!! — Countdown to Music's Biggest Night" will air live on November 30 at 10 p.m. ET/PT on CBS.
