Irish rockers U2 will be joined by R&B diva Mary J. Blige as one of several big name collaborations during the upcoming 48th annual Grammy Awards. Also due to pair up on stage are Faith Hill and Keith Urban, Christina Aguilera and Herbie Hancock and Jamie Foxx with previously announced performer Kanye West.

Although specific songs have yet to be confirmed, it seems likely U2 and Blige will reprise their cover of the latter's "One," the studio version of which appeared on Blige's recent album, "The Breakthrough." Last year, Aguilera sang on "A Song for You" from Hancock's latest album, "Possibilities."

West and his fellow lead nominees Mariah Carey and John Legend were the first confirmed artists for the Feb. 8 show, which will take place at Los Angeles' Staples Center and be broadcast live on CBS. As previously reported, all three are tied with eight nominations.

Additionally, the Recording Academy has confirmed the show's first presenters: country duo Big & Rich and actors Tom Hanks ("The DaVinci Code") and Terrence Howard ("Get Rich or Die Tryin'").
