Rap, rock, country, pop at Grammys


Lil Wayne, Coldplay, Jonas Brothers, Kenny Chesney and Katy Perry are the first performers announced for the 51st annual Grammy Awards.

Perry's performance will be interactive. Fans can upload videos up to a minute long of themselves singing along to her hit "I Kissed a Girl" to CBS.com/Grammys through Feb. 6; voting will determine which of them will be shown during Perry's segment.

Each of the performers is nominated for awards. Lil Wayne leads the field with eight noms; Coldplay is next with seven. Both are up for album of the year.

CBS will broadcast the show Feb. 8 from Staples Center in Los Angeles.

Jonathan Cohen is senior editor at Billboard.
