Add Christina Aguilera, Mary J. Blige and Ludacris to the list of superstars who will be performing at this year's Grammy Awards on February 11. The singers join the latest lineup for the 49th annual awards show, which will also include former "American Idol" Carrie Underwood and two performances by Justin Timberlake.
The artists will take the stage for a night of music that was already scheduled to include Beyoncé, the Dixie Chicks, Gnarls Barkley and the Red Hot Chili Peppers (see "Beyonce, Chili Peppers, Gnarls Barkley To Perform At Grammys"). The Black Eyed Peas, Ciara and Nelly Furtado will help hand out awards.
It's fitting that Blige take the stage, as she's the leading Grammy contender with eight nominations (see "Mary J. Blige, Chili Peppers Top Grammy Nominations List"), including Record of the Year, Song of the Year, Best R&B Song and Best Female R&B Vocal Performance for "Be Without You," Best R&B Album for The Breakthrough, Best R&B Performance by a Duo or Group With Vocals (Jamie Foxx featuring Mary J. Blige for "Love Changes"), Best Pop Collaboration With Vocals (with U2 for "One") and Best Traditional R&B Vocal Performance ("I Found My Everything").
Timberlake, who was previously set to perform with the winner of the My Grammy Moment contest, will now also take the stage for a show of his own. The singer is up for four Grammys, including Album of the Year and Best Pop Vocal Album for his second solo effort, FutureSex/LoveSounds, Best Rap/Sung Collaboration for "My Love" featuring T.I., and Best Dance Recording for "Sexyback."
Luda's also got four nods, for Best Rap/Sung Collaboration for "Unpredictable" with Jamie Foxx, Best Rap Performance By A Duo or Group for "Georgia" (with Field Mob and featuring Jamie Foxx), Best Rap Album for Release Therapy and Best Rap Song for "Moneymaker."
Aguilera has two nominations, for Best Female Pop Vocal Performance for "Ain't No Other Man," and Best Pop Vocal Album for Back to Basics.
Underwood, whose Some Hearts is the fastest-selling debut country album in the SoundScan era (which began in 1991), is nominated for Best New Artist and Best Country Female Vocal Performance for "Jesus, Take the Wheel."
