Rihanna, Sam Smith, Madonna to Perform at iHeartRadio Music Awards This Sunday

Do you "heart" music? Then don’t miss the second annual iHeartRadio Music Awards, coming up Sunday, March 29.

Pop artists, country singers, rappers and more will unite at the Shrine Auditorium in Los Angeles celebrate the biggest names (or voices) in entertainment. The show is hosted by Academy Award and Grammy winner Jamie Foxx, a true entertainment double threat.

Rihanna, Iggy Azalea, Sam Smith, Madonna, Kelly Clarkson, Snoop Dogg, Jennifer Hudson and Meghan Trainor are a few of the stars expected to take to the stage. You should also expect "never-before-done duets and collaborations," say iHeartRadio Awards planners.

It’s tough competition out there: Ariana Grande, Iggy Azalea, Luke Bryan, Sam Smith and Taylor Swift are all up for the Artist of the Year Award.

See all nominees here, and tune into the awards this Sunday on NBC.
