The Grammy producers like unusual pairings. A couple years ago, it was Eminem and Elton John duetting on the rapper's ''Stan.'' Last year, alt-rocker Dave Grohl joined Elvis Costello and E-Streeters Bruce Springsteen and Steve Van Zandt for a tribute to the late Clash frontman Joe Strummer. This year, it'll be Grohl's Foo Fighters performing with jazz pianist Chick Corea, Billboard reports. They'll join a performing roster that already includes a Sting-Sean Paul duet. Also newly added to the bill is a tribute to the ailing Luther Vandross, a two-song set to be performed by Alicia Keys, Celine Dion, and, um, Richard Marx. Another new addition to the lineup is 50 Cent, but the rapper will apparently be performing solo.
Others added to the program, as awards presenters, are Aerosmith's Steven Tyler and Joe Perry, Hilary Duff, Faith Hill, B.B. King, Brian McKnight, Carlos Santana, and jazz singer Kurt Elling.
Previously announced performers include the White Stripes, Justin Timberlake, Christina Aguilera, OutKast, George Clinton, and Martina McBride. Previously announced presenters include Norah Jones, John Mayer, the Neptunes' Pharrell Williams, hobbit Sean Astin, and teen mystic Amber Tamblyn. The show airs live on CBS on Feb. 8.
