Rihanna, Timberlake and Kendrick Lamar Among iHeartRadio Awards Nominees

Mark your calendars. A new award show will debut this Spring on NBC. Following successful efforts, including the iHeartRadio Music Festival, Clear Channel will launch the first ever iHeartRadio Music Awards May 1.

With 13 categories, including Song of the Year and Best Collaboration, fans will choose who wins these awards.

Initial nominees include Rihanna, Justin Timberlake, Kendrick Lamar, August Alsina and Robin Thicke.

"Each voting category initially features 10 nominees – listeners will then narrow down to five finalists during a four-week period, with the finalists to be announced during a one-hour special live event on March 26, 2014 at the iHeartRadio Theater in Los Angeles. Fans will then vote over the next several weeks, to determine the winners in each category," iHeartRadio reports.

The iHeartRadio Music Awards air live from Los Angeles May 1st on NBC. The show, which will feature performances from other Los Angeles venues, will also broadcast and stream live across all participating Clear Channel radio stations and their websites, and on iHeartRadio.
