Multiple nominees Feist, Alicia Keys and Brad Paisley have joined the performance lineup for the 50th Grammy Awards, to be held Feb. 10 at Los Angeles' Staples Center. In addition, the casts of the film "Across the Universe" and "The Beatles LOVE by Cirque du Soleil" will participate in a Beatles segment.

Newly announced award presenters include Natalie Cole, Juanes, Cyndi Lauper, Bette Midler and Bonnie Raitt.

Beyonce, Foo Fighters, Carrie Underwood, Aretha Franklin, Mary J. Blige, the Clark Sisters, Israel and New Breed, Trin-I-Tee 5:7, Rihanna and the Time will also perform at the Grammys.

The industry breathed a lot easier earlier this week after the Writers' Guild of America struck an interim deal with Grammy producers, ensuring the show would move forward despite the ongoing writers' strike.
