GET YOUR iHEART ON

Be sure to set those DVRs, 'cause the iHeartRadio Music Awards are a-comin'. The highly anticipated happening airs this Sunday (3/29) on NBC from the Shrine Auditorium at 8-11pm ET/PT.

Word has it that Iggy Azalea will open the show, which will be hosted by Jamie Foxx and presented by iHeartMedia.

You can also expect Rihanna's first performance of new single "Bitch Better Have My Money," along with performances from Sam Smith, Madonna, Jason Aldean, Jamie Foxx, Meghan Trainor, Jason Derulo, Jennifer Hudson, Kelly Clarkson, Snoop Dogg, Nate Reuss and Florida Georgia Line. Meanwhile, Alesso will be the evening's resident DJ.

And you know Taylor Swift will be dancing to every minute of it all.

Did we mention that Justin Timberlake will be there as well? The heartthrob's set to receive the 2015 iHeartRadio Innovator Award. And we're set to be really stoned during his undoubtedly charming acceptance speech. Set your Shazam to "stun" and let's do this.
