U2 [ tickets ], Mary J. Blige [ tickets ], Faith Hill [ tickets ], Keith Urban, Christina Aguilera [ tickets ], Herbie Hancock [ tickets ] and Jamie Foxx have all signed on to give collaborative performances at next month's Grammy Awards ceremony.

U2 and Blige will hit the stage together for a joint performance, as will Urban and Hill, Foxx and West, and Aguilera and Hancock.

Organizers did not specify what songs the artists would perform, but it's a good bet that previous Grammy winngers U2 and Blige will offer up a rendition of the Irish rock group's classic hit "One," which Blige covered on her most recent album, "The Breakthrough."

Foxx is featured on West's 2005 smash hit "Gold Digger," and Aguilera sang on the Grammy-nominated cut "A Song for You," which appeared on Hancock's latest album, "Possibilities."

U2, whose trophy case already houses 15 Grammy trophies, is in contention for five more at this year's ceremony: Album of the Year and Best Rock Album ("How to Dismantle an Atomic Bomb"); Song of the Year and Best Rock Performance by a Duo or Group with Vocals ("Sometimes You Can't Make It On Your Own"); and Best Rock Song ("City of Blinding Lights").

Hill, a four-time Grammy winner, is vying for Best Female Country Vocal Performance ("Mississippi Girl"), Best Country Collaboration with Vocals ("Like We Never Loved At All" with Tim McGraw), and Best Country Album ("Fireflies"). Urban is up for Best Male Country Vocal Performance ("You'll Think of Me").

Aguilera and Hancock hope to share a win in the Best Pop Collaboration category for "A Song for You."

Singer-turned-actor-turned-singer Foxx has a nod in the Best Male R&B Vocal Performance category for "Creepin'," a track from "So Amazing: An All-Star Tribute to Luther Vandross," and shares nominations with West for "Gold Digger" in the Best Rap Solo Performance and Record of the Year categories.

As previously reported, West is nominated in a total of eight categories, as are fellow previously announced Grammy performers Mariah Carey and John Legend.

In addition to the new batch of performers, Grammy organizers also announced that country duo Big & Rich, along with actors Tom hanks and Terrence Howard, will appear as presenters.

Additional performers and presenters will be announced shortly, according to a press release.

The 48th annual Grammy Awards ceremony takes place Feb. 8 at the Staples Center in Los Angeles, and will air live on CBS-TV.
